Underfolk

The underfolk are descendants of bands of humans who chose-or were forced-to live in the caves and twisting passageways of the underground world. Over generations, these humans adapted to this strange world, filled with natural wonders and dangerous creatures. Some underfolk societies have not ventured to the surface in generations, and others have forgotten their true origins altogether. However, those who live close to the caves that give entry to the underground realms make occasional forays to the surface and even engage in limited trade with surfacedwelling humans. Underfolk are a simple, clannish people dedicated to their homes and the safety of their race. Because of the multitude of evil and predatory races and creatures in the caves and tunnels they call home, underfolk have become quick, stealthy, and survival-oriented. Although rather primitive and rustic when it comes to technology, underfolk make up for this lack with a superior knowledge of how to survive beneath ground, although even they avoid the deepest depths of the subterranean realms.
