Ghast

The shambling, simian mounts of Vye and northern Gasmithon are clearly descended from human stock. Ghasts are slower than horses, but more enduring, and many walled-in defenders have been dismayed to discover they climb very well, even with a rider. Ghasts are omnivorous and can live thirty years or longer.

They are generally dull-witted but show occasional bursts of cunning and clarity, a tendency which their handlers keep watch on, wary of wights.
