Appearance. The Téi'Hái (also called "Magic Demon" or "Mage Bane") is a towering bulk of terror: 3.5 peds tall, 1 ped from shoulder to shoulder, sickly yellow skin, a mouth of dagger-like teeth, and able to crush the head of an orc by wrapping a hand around it and squeezing it. Eyes, close together on the head, blaze purple. An oddly narrow nose seperate the eyes, and though it looks small it can still sniff out practically anything. Muscles ripple beneath the skin, and veins pulse with a blue, viscous liquid which most claim is blood. Every twelve fingernail widths two spikes protrude from its back, on leaning to each side. It is something out of nightmares, and it exists.

Special Abilities. The only real special ability of the Magic Demon is its saliva. When it chooses to, it salivates a strong acid, which it can spit with deadly accuracy. It will melt the skin right off the bone, and then the bones will follow. It also has strength greatly above that of humans, though by the looks of it that doesn't seem very special, but rather something you'd expect...

Territory. The Téi'Hái have no real territory. If they want territory, they take it. Though there have only been a handful in existence, so maybe they do have a certain territory they like, but it hasn't been discovered yet if they do. But if one of these things comes and seems to claim your land as its own, let it. Just leave.

Habitat/Behaviour. Téi'Hái kill. They eat. They sleep. But mostly kill. Not much more to their behavior than that. Of course, they will do the bidding of the person who summoned them, but they'll kill that person at the first chance they get if the person isn't strong enough to keep one under control.

Diet. Téí'háí eat... well, anything. Meat, vegetables, wood, metal, clothes, anything. It's unknown how their bodies can get nutrition from some things, or if they even need it to, but they can eat it. As for digesting, no one knows, because no one has ever seen any excrement from this creature. The leading theory is that the things simply dissolve in the Téí'háí's stomach and sit there until it needs the acid in its saliva.

Mating. Téí'háí don't mate. They are summoned. A mage puts down the body of a dead person, performs the right demonology ritual, and the thing's spirit will inhabit the body. Within a matter of seconds the body is transformed into what you see if you meet a Magic Demon. That is how they come into Caelereth.

Origin. Téí'háí were first brought into Caelereth by the demonologist Ynath of Strata. This is widely thought of as a terrible decision. It was, make no mistake, but it granted him great power. Until the demon killed him.

Researchers. Geta Siiken, the famous Chasm Demon researcher, did the main study on the first demon after it was finally captured. Retained by powerful magic spells in a secret location within Ximax he watched its behaviour, gave it things to eat, exposed it to disease, and recorded it all. The final book on these demons rests in the Ximaxian library.
