Trebhum

The Trebhum are a tribal race of bipedal creatures. The current status of the species is unclear due to the involvement of the Eternal Cylinder.

Biology
The Trebhum are considered fairly low on the food chain due to their smaller size. In their default forms, Trebhum have rounded bodies and a set of legs with large, flattened feet for basic locomotion. Their most prominent feature is their elongated snouts, which they are capable of using to either feed, or to carry smaller objects in a similar manor to elephantine trunks.

Trebhums have also evolved a storage sac within their own bodies, allowing the creature to store away food for a later date. Food within this sac can remain fresh for a long period of time, and can be shared amongst other Trebhums.

Shape-Shifting
The most unique ability that the Trebhum possess is their ability to shape-shift, as means to adapt to different environments and predation pressures. This form of shape-shifting was once able to be done by pure will, but thanks to the involvement of the Servants of the Eternal Cylinder, this ability has been severely weakened, and currently still being taken away from them.

In modern times, the Trebhum's main means of shape-shifting (otherwise known as "Mutation") is to consume particular materials that would trigger specific mutations. Most of these are of organic origin, and numerous other forms and mutations had been documented over numerous studies of the Trebhum:

Culture and society
The Trebhum are sociable creatures, not meant to be alone, and constantly found in various groups. The Trebhum have hardly, if ever, been observed alone and hold great bonds with one another. These creatures communicate with each other through trumpeting calls and grunts.

As far as the actual culture of the Trebhums go, most of it has long been ancient, and hidden within shrines and caves rather than out in the open. These shrines are presumably built by the Trebhum, but this is speculative at current state. Younger Trebhums gather in such places to be safe from predators, and share genetic memories with one another, along with knowledge gained from a Trebhum Elder. The race has various folk lore stories involving the creatures outside, such as the Zooshgarg.
