Tenetic ('Ancient Ones' in their dialect) consider themselves to be the original ancestors of all Verdimm. Other Verdimm are viewed as essentially unruly children. Tenetic are peaceful, shy, stoic, and usually dangerous only if another tribe member, particularly a child or mate, is threatened. Members of the close knit tribe nest together in deep milder mountain valleys amonst piles of decaying leaves near the sacred resting places of their ancestors. Leadership comes from the elder's council (Na'Gri), overseen by the leader (Pa'Gri). They will provide shelter and protection to any individuals or small parties who seek it within their territory, provided no threat is perceived. Their trust is difficult to earn, but once earned they are truly dependable. Excellent craftsmen with stone and minerals, they construct most of their weapons, jewelry, and any art forms froms these materials, as well as employing them as elements in magic and ritual.

Tenetic in any form are very strong and muscular and will generally have some gray hue in their appearance such as skin or eye color. The Dimoh form (preferred when outside the tribe) is a tall basically human appearance. The Khiulnter form (preferred for use within the tribe) is a large quadruped, with gray leathery skin and bat-like wings, heavy hand-shaped claws, and demonic faces. In this form they are capable of fast, but not very maneuverable flight. In Dimo-Khu (preferred primarily for ritual), they possess the Dimoh lower body and limbs, the Khiulnter wings (capable only of gliding), heavy clawed hands and face.
