Becoming lost in the Underdark is a fate worse than death. Descendants of such folk go blind, their skins turned to thick grey, and lose all sense of self and civilization -- they become grimlocks. Degenerated to little more than hulking barbarians, grimlocks wander the Underdark searching for for food, shelter, and clean water. While not inherently evil, grimlocks will do anything to survive -- including smashing skulls and eating corpses. Grimlocks live in loose clans and can speak a variety of languages, though their dialects are often twisted descendants of mother tongues. Instinct: Survive at any cost

• Wander the underdark
• Smash with an axe
• Beg, steal and borrow
