Cephalossk was the ulitharid Creedmaster of the Venerators Creed in Oryndoll by 1370 DR[1] and through 1372 DR.[2] Its position and its powers made Cephalossk the second most powerful individual in the city.[1]


Cephalossk was the leader of the Creed of the Venerators, and so the high priest of Ilsensine and a member of the Elder Concord during the Time of Troubles of 1358 DR when the avatar of Ilsensine manifested in Oryndoll.[1]

In the early 1490s DR, however, Cephalossk had become a pariah among his own kind for his desire to become an arcanist. He went to study at the magic academy of Dweomercore inside Undermountain.[3]


Like its fellow Elders, Cephalossk received a pair of tendril rings of Ilsensine. However, these rings had additional, secret powers, many not yet known even to Cephalossk and which it was still learning.[1]


Cephalossk had a constant mental link with the Encephalithid.[1]
