Lurker

Lurkers are wicked by nature, and lacking in intellect. The first tribes of the Shudder Mountains were pushed to the brink of extinction, but some clans survived in their new troglodytic world, adapting to the darkness. Whether these survivors discovered the descendants of their ancient serpent-men enemies and joined in battle once again is unknown, but explorers of the Black Mountain caves have reported encounters with a savage, human-like species of cannibals ideally suited for underground existence. These creatures may be the ancestors of the Shudder's first human occupants, now long devolved. They are called the Lurkers.
