M'yeah, closed ecosystems, the bane of every fresh developer (myself not excluded, i might add, although i like to think i've later seen the rror of my ways there)
Perab, a big portion of the problems with your entries comes from the fact that you're creating one of aforementioned 'closed ecosystems', a region with as little interaction with its surroundings as possible, with no historical, geographical, ecological or demographical ties to anything we've already established. While the basic work may have merit, we do require every new addition to be fully connected with what we already have.
In the end, that is probably going to take several changes in your basic concepts. This is also the reason we encourage new contributors to start with entries on plants, beasts, or miscelaneous objects, and to pick something -unrelated- to their own ideas.
I think that making a few of such random contributions helps you get a feel for the established world as it is, as well as forcing you to read up on just about everything, and practice interweaving new ideas with the old ones.
Oh bloody... now i'l have to cross-refer the entry to the racial histories and check your work! This means i'm going to have to actually *shudders* do some work again.
Stay tuned, this might take a little while (busy busy busy life at the moment, with spatial relocations (also known as; they're tearing my home down and i have to move) and job-related crazyness about. That, and my body is trying to get a good ol'fashioned flu. I keep telling it not to, but it's being stubborn again.)
And ISSO simply means "Because it IS SO.." In this case, it has been decided that there is no gold in the enclave, or on that side of the mountains, for all it's worth. Things get based on that assumption, etc etc. You can't go back later and add some gold, even if it would be geologically viable, because we've already said it's not that way. ISSO.
