Crevasi

No pilot has ever seen a crevasus.

Crevasi are a sub-species of pegasus, adapted to live deep in the chasms and far below the layers of mist. Their wings, now all but featherless, have been re-purposed as an additional set of legs. They use these to help traverse the steep walls and floors of the chasms. They have developed numerous physical adaptions to cope with their dark and difficult environment: small amounts of bioluminescence, which they use to not only see with, but also to form and maintain social bonds. Larger eyes, or multiple eyes that capture infrared light. Large, sensitive ears. Feet with 2-3 toes to help grip the walls. These and others are common adaptions.

Crevasi can be as small as a pony or as large as the average broadwing. The larger specimens are slow and graceful, able to reach the fungi, mosses, and lichens that thrive in the low-light, high-moisture environment of the chasms. Smaller crevasi move quickly to chase small prey, such as bugs or small lizard-like creatures. It is unknown if the smaller ones eventually grow to be big, or if they are a different breed.

Primarily solitary, these creatures will occasionally congregate in small bands, family groups, or sibling pairs. A crevasus foal will stay with its dam for up to a full year, but will generally strike out on its own shortly thereafter, and may never meet with any of its blood relitaves again. Fights among crevasi are extremely rare, as their population is small and rather spread out. The lifespan of a crevasus is unknown.

As mentioned above, no human in the Sky Cowboys world has ever seen a crevasus. Only once they have the ability to survive the journey below the Mist will the unique ecosystem of the chasms be discovered, and the crevasus with it.
