Ancient Ones
Transmogrified beings who have passed through the Ultimate Gate guarded by Tawil at'Umr. Though originally of many different species, they appear in Tawil at'Umr's great temple as cloaked, sleeping figures bearing scepters and seated on pedestals. The Ancient Ones only wake to aid those who desire to enter the Ultimate Gate and join their number. It may be that the Ancient Ones are the Great Old Ones themselves. See 'Umr at-Tawil; Vatican Codex. ("Through the Gates of the Silver Key", Lovecraft and Price.)
