Trelanx are hairy humanoids with two vestigial horns. They stand about 7 feet tall and weigh about 300 pounds. They generally do not wear clothes, but sometimes wear pouches or packs acquired from other races. They speak their own language, though some have learned a few words in the Common tongue.

They live in tribes deep in the forest. They make huts and aggressively defend their lands. Unfortunately, some have been enslaved by evil wizards and Clerics to use as brute labor and as guards.

In combat, they will throw flint-knapped spears and then attack with both claws. Their horns also provide a limited form of mind reading such that they cannot be surprised. They have Darkvision up to 60 feet above ground; there must be some ambient light present.
