This illustration is from my Kickstarter project to create drawings of all of the friendly nonhumans and land animals from Professor M.A.R. Barker's wonderful Tékumel (aka Empire of the Petal Throne) role-playing world setting.
"These are mutants made from some member of the ancient ape stock of Earth by the Priests of Ksárul. They are roughly humanoid in shape, with long, sharp jaws and sharp teeth, a rudimentary nose, and large jewel-like round eyes beneath beetling brows. They will attack parties which they outnumber but will run away if the party is more than equal to them. They fight with club and spear, and although they are semi-intelligent, they cannot be trained."
