Here's the entry modified to refer exclusively to the tribe instead of the kingdom.

Diet-
                The Avennorian Diet is composed primarily of seafood, particularly yellowtail and oyster for the common folk and malkut king fish for the more wealthy, although most of those who can afford a king fish can also afford to import meats from the neighbouring province of Sanguia, among other imported goods, which are usually considered more high class in Avennorian society. It should be mentioned, however, that there is some small scale farming within Manthria, the biggest being the Twynor farmsteadings. A staple of all Avennorian diets is flysh seaweed, which is used as a base for many Avennorian dishes or is baked into a bread. Another traditional import among the Avennorian people are the products of Eyelian agriculture, as they serve as a refreshing change to the monotony of seafood that is so common in Avennorian culture.

Occupations-
                Traditionally, Avennorians are primarily fishermen, pearl divers, whalers, and merchants, though of course all of the miscellaneous jobs for each town are, and have always been, available (blacksmiths, jewellers, etc.)

Fishers and Whalers-
                These are the biggest industries of the province of Manthria, though that doesn't mean that they are its best paying ones. Whaling is slightly better paid, as whale products are Manthria's largest export, though it is still considered a commoner's job. Fishing and whaling employ a large portion of working class Avennorians, who have colloquially titled themselves "Harvesters of Baveras' Bounty". The people in these jobs make up the backbone of the flourishing Avennorian economy, a fact which they never cease to pride themselves in.

Pearl Divers-
               Pearls were one of the kingdom of Avennoria's most famous products, and today one of Manthria's most sought-after goods.. Merchants from all over Sarvonia come to the port of Ciosa or the city of Marcogg to trade for high quality Avennorian pearls. Pearl divers are the ones behind this large sphere of influence held by Avennorian traders. It was originally through trade of pearls that Avennorian cities became the bustling hubs of trade they are today. Pearl divers themselves are more respected than fishermen and whalers, particularly those who are able to close their ears to enhance their skills.

Merchants-
                Merchants are the smallest, but most influential, group among the Avennorians. They are the cause of the image of Avennorians as a whole being that of wealthy and powerful, albeit somewhat ruthless, traders. For an Avennorian, being a merchant means doing what you need to do to get to the top. Though they make up only a small portion of their society, they regard themselves as being superior to all the social classes below them, to the point of considering themselves above the law and/or their own human morality, or at least that's how the rest of their society views them. When one of them was asked about how they felt about this representation of them by the author, they laughed and said that the masses were "naught but jealous swine who believe they should be treated as human."

Government-
                Prior to joining the United Kingdom of Santharia, Avennoria was ruled by an aristocracy where the person with the most wealth usually became king. Because this requires the king to remain the wealthiest over the course of their rule, it was not impossible for the king to get overthrown purely on the basis of temporary shortages in his/her flow of income. However, it was also not a frequent event, so most of the time, the king could simply pass his/her wealth onto the next generation in his line without trouble, sometimes for four or five generations in a row.
                Due to this form of government not requiring any leadership skills to become king, kings were, more often than not, much better businessmen then they were governors. This usually led to lots of back door dealings, including, but most definitely not limited to, buying government jobs, using parts of -and in some cases - the entire - kingdom as collateral, passing laws for the highest bidder, and, in one circumstance, renting out the position of king for a "small" fee to those who were willing to keep their mouths shut on matters that were never disclosed, even to this day.

Ok, a few questions.
First of all, you're planning on making these real beings and not just myths, right? If you are, my suggestions are:
1. Find an area of Caelereth or a group of people that would fit its purpose.
2. Try to answer the 5 Ws to the best of your ability.
3. Then, try to think what effects such a being might have on the world around it. In particular, you may want to try and find an instance in the compendium when knowledge that should have been lost with someone's death was put in the compendium anyway without providing a reason. That shouldn't be too hard to find, but make sure adding your apparition wouldn't cause contradictions or massive plot holes.

From there, just develop some of your own lore around them. Don't plagiarize the Calacas ability for ability, put your own influence into the story

Secondly, what does their singing sound like? Is it clear or only vaguely human?

Lastly, for whom do they appear? Is it everyone or only heroes? Also, are they visible?

Just a few things to get you started. Happy Writing!

Weaving as a dimension is a little problematic though, since weaving is primarily an inborn skill, so having all Memnoor able to learn it would be hard to explain. Arti's idea of "possibility" is usable instead, as knowing where in "possibility" something is is at least a little more feasible. Maybe we could take something of a "many worlds interpretation" look, where each alternate world along this axis is just the same world, but with slightly different events, but the same basic beginning (i.e. parallel universes). For example, a utopia could be born of a world where Áva takes direct control, etc. (This could also explain the sometimes maybe kinda existing Netherworld.)

Dimensions list as I see it:
1-4
5. Imagination
6. Emotion (could be replaced with life force/energy)
7. Possibility
8. ?????

For 8, I would suggest maybe Fundamentals??? As in, the basic laws and ways of the universe. In terms of the real world, these would be the laws of physics, but in Caelereth, they could also include the inherent duality of the world. Áva and Có'or may even be physical beings in that world, though that may be a bit of a stretch...

Ok then, you do you I guess... ...  Just kidding, it's all in good fun. Don't worry Arti, we're not insane... yet 

  Hail Lord Enlil 

*chuckle* Aww Ven, you're making me blush already. No need for the formalities by the way, just call me Doomy. Seriously though, good to have you here, and based on what you suggested, you're just as insane and demon obsessed as I am. Gooood.......

Why hello there! Just got here recently as well, nice to meet you!  I'm sure Artimidor (the all powerful webmaster) will give you a more formal introduction, but until then, welcome to the forums! 

Wonderful! Looking forward to getting to know the region  ...

Ok, modifications complete.
1. Removed (most) technobabble
2. Added magibabble
3. Fixed some trivial things (spellings, apostrophes, etc)
4. Changed Origins section to Myth/Lore, moved the mystran thing there
5. Invented an eleven word for neurotoxin
6. Modified various smaller things (wordings, etc)

Should I add some kind of backstory to the whole mystran thing? It feels incomplete, but then again, authorial bias, not to mention my tendency to babble a little in any writing, as you saw in the Description section.

Thanks for all the commentary, I'll try to work in all this somehow. Sad I have to get rid of my technobabble though. You will be missed. RIP technobabble. Right, not too gloomy Doomy. You can do this. Seriously though, thanks. Now, to work!!!!!!

Also, I can't help but notice that you seem to have a love-hate relationship with the apostrophe. On one side, we have elvish, with an apostrophe every two letters, then on the other, we here have you telling me to change "It's" to "it is". I'm fine with it, just saying.

Finally, somewhere where my copious amounts of pointless quantum physics knowledge may finally come in handy! But seriously, let's brainstorm a little. Imagination is definitely number 5, as the Void's own entry hints. After that, maybe emotion? And if we really want to follow some vague semblance of real physics (I don't care if we do, Kareesh just brought it up), "strings" from weaving magic could be one. Another concept from real world is that energy is physical in a higher dimension. In terms of Caelereth, this could be magical energy, particularly elemental, or, more logical for a Brownie to be able to manipulate, life energy. Still don't know what an eighth one would be, but that is only needed some of the time, so the first user wouldn't necessarily know about it, at least not until far later, and even then, we could just cop out and say it is physically impossible to comprehend without experience in the void. That's essentially how physicists describe higher dimensions anyway, though in physics, all dimensions are physical, so a dimension for imagination makes no sense in the real world anyhow.

Oh, and by the way, that's 11 dimensions in strong theory

I don't know if this thread is still being used, but if it is, can I reserve the Avennorian Diet, Occupations and Government sections? I want to get into some Tribe things, but a full tribe entry is way too big of a project, at least for now, so I figured, why not do some quick revisions, plus it'll help me get acquainted with Manthria and southern Sarvonia as a whole.

So I was wondering if I could do a Person entry on the first Brownie to explore the void. All the entry says is that the Memnoor eventually got used to straddling the void. The Ethereal Void entry mentions that coordinates within the void are based on seven dimensions, sometimes eight, so I wanted to write about a guy who has to discover these on his own after stumbling into another world wholly by accident. The only dimension we know beyond our naturalistic four is presumably imagination, but we have no idea what the rest of them are.  Are they all mental, or are some of them beyond Earthly comprehension? Do we know? Do the Memnoor know? If they do, can they describe them? So many questions!!! !

Ok, hopefully that's spaced a little better now.   

Category- Medicinal herbs -->Poisonous Herbs. The herb is already in the overview, but it doesn't have an entry yet.

Overview-
              The Cylian Poppy is a flowering plant with blindingly bright white petals surrounding an iridescent gold coloured center. The foliage is jagged, spiky and sharp enough to latch onto leather without trouble. It is mainly used for its thick, milky sap, which is a highly addictive narcotic, and a rather strong one at that, but can also be used in deadly brews with the right levels of skill, which is colloquially known as "Murdrum" in certain cities.

Description-
              The Cylian Poppy is usually approximately two fores high at its maximum height in the summer when it flourishes, but it can retract to as small as one palmspan during the colder seasons. The stem is rather thin (around one nailsbreadth), allowing the plant to swing around as it needs to to latch onto its prey, which it latches onto with its leaves and leeches off of for food while simultaneously releasing a powerful shatír'ó'chón'cár (lit: winged spirit) into the subject's body, not only numbing them to the pain, but also causing them to fall asleep while still in the plant's grasp.
              It should be noted that this effect seems to be amplified based on the level of sentience of the subject. Creatures with extremely high levels of sentience, such as elves and men, have even been known to become unknowingly addicted to the shatír'ó'chón'cár and felt compelled to wander the area where they had been caught in the plant's trap until they got caught in another one. This, after a few months, usually results in the death of the victim, unless they first realize that what compels them to keep visiting the area is, indeed, their addiction to the flowers drug, which is a near impossibility when they as they become mindless slaves to the plants by coming within five peds of it due to what is assumed to be some sort of aura emitted from it, making it mighty hard to escape the call of the Poppy.
              The leaves of the plant seem to have pulsating veins all over them and can vary in length from three nailsbreadths to a full palmspan. The radius of the flower, however, is always around one third larger than that, so as to hide the leaves from any people, whatever race they may be, and to lure them into its trap. The Cylian Poppy flourishes in warmer climates, but can retract its stem to avoid over exposing itself to the cold should conditions temporarily cool. That said, the poppy should never be  exposed to conditions too far below the freezing point of water for more than two moons, or it will shrivel up to a nailsbreadth and not come back up until conditions of room temperature or better are reached or it dies for lack of food.

Territory-
              The Cylian Poppy is found only within one league's radius of the Thaelon forest, particularly around Ephirn's Lake, where it is believed to have originated. It is unknown exactly how far the plant grows from the lake in each direction due to the likelihood of a researcher accidentally getting addicted during their research. They are able to escape the plant's grasp because of their knowledge of its effects, but they must separate themselves from their research permanently in order to avoid any residue shatír'ó'chón'cár affecting them.

Usages-
              The most common usage of the Cylian Poppy is as a narcotic, which is administered either using the leaf in its basic form or through the extracted sap, which is often modified with a pinch of forget-me-nut powder to remove the urge to go on a quest to Ephirn's Lake, a side effect of the drug which made early dealers of the drug lose customers rather quickly. However, every once in a while, dealers of the drug will "forget" to add the forget-me-nut powder to the drug, and the user is sacrificed to the plants to keep them alive after constantly being drained of their sap. The drug can also be refined to the point of causing the brain of the user to shut down completely, creating an instant and untraceable death.
              The entire plant is believed to have connection to the Netherworld, though again, this is just unverified superstition, as are most things concerning the Netherworld. The sap is believed to be usable in a brew with some vaninen concoction, a touch of veell elixir, and a few ods of wizardleaf for a frightening potion that, upon lighting, is said to summon a mystran hoard large enough to take out a small town in minutes and haunt it for years on end. This may be mere myth however, because no known person has ever lit one of these and lived to tell of it, which, given the power of a mystran, should not be incredibly surprising.(Moved to Myth/Lore section)

Reproduction-
              The reproduction of the Cylian Poppy is just as confusing as any other part of it; it sends spores into the body of a victim who's died while still attached to the leaf of the plant they were killed by. If a victim of the Poppy dies from the  from the plant, the plant senses the lack of pulse and releases chemicalspulses of aura to speed up the decomposition of the body, before releasing tiny spores into the body, which, once inside, reassemble into a seed like structure, which eventually grows into a new flower.
              Due to this form of reproduction requiring new generations to grow no more than a few fores away from the previous, the plants often grow in thick clumps that dot the Thaelon forest. The plant can spread further, however, if it mistakes an incredibly deep sleep for death and sends spores into the host while it is still alive, who, with any luck, will move around the forest, spreading the plant's seed. It should be noted, however, that the plant can't live too far outside the Thaelon forest. Travelers have been found dead on the roads a few leagues from the forest with traces of Cylian Poppy spores in their body. In these cases, the spores appear to be shriveled up, leading many to draw a line directly outside of the forest and declare it the extent of the plant's growth.

Myth/Lore-
              Although it is unknown exactly how the Cylian Poppy originated, an interesting tale concerning the subject is held by some of the people in Carmalad. They believe that the plant is born of the spirit of Ephirn that was created when the light elves refused to perform their Rite of Return on him, but instead sunk him in what is now known as Ephirn's Lake. They believe that his spirit, still searching for the human woman he sought after his life ended, continues to search for her, only to be continuously foiled by the boundaries of the Thaelon forest. Other stories state that the reasons for the existence of Ephirn's spirit aren't quite so romantic. They say that either his spirit is angry for his death or the spirit is composed of all the hatred of humanity he'd pent up over years of assisting humans, who he considered less than him. The last one, however, is usually held by those with a hatred towards elves in general, and is the least common of these fables.
              The entire plant is believed to have connection to the Netherworld, though again, this is just unverified superstition, as are most things concerning the Netherworld. The sap is believed to be usable in a brew with some vaninen concoction, a touch of veell elixir, and a few ods of wizardleaf for a frightening potion that, upon lighting, is said to summon a mystran hoard large enough to take out a small town in minutes and haunt it for years on end. This may be mere myth however, because no known person has ever lit one of these andbeen fool enough to light one of these, and if they have, they haven't lived to tell of it, which, given the power of a mystran, should not be incredibly surprising.
