Tilder were herd animals with curling horns, a speckled hide, a bony upper lip, and size comparable to that of a deer. They were herbivorous and could often be found by water. Tilderflies were often found close to herds of tilder. The horns of the tilder could be made into trumpet-like instruments called tilderhorns, their meat was eaten, their skin was tanned into tilderleather, and their wool was used for cloth. A variant that appeared in the Farrow Ridges, in Doombringer, had four horns.
