Barlgura

Overview
The Barlgura represents the savagery and brutality of the Abyss. Barlguras gather in packs to take down tougher foes, keep gruesome trophies from their victories, and decorate their territory with such objects.

A barlgura looks like a hulking orangutan with gruesome, drooping visage and tusks jutting from its jaw. Standing just under 8 feet tall, it has broad shoulders and weighs 650 pounds. It moves apishly along the ground, but it climbs with great speed an agility.

Abyssal
Though demons all have common names, every deamon lord and every demon has a true name that it keeps secret. A true name represents the bloodline of a demon. A unique and powerful true name usually represents the power of a demon. A demon can be forced to disclose its true name if chamred, and ancient scrolls and tomes are said to exist that list the true names of the most powerful demons.

A being that learns of a demon's true name can call upon it to control the demon and summon it from the Abyss.
