Zeph'gorog
Guardian of the Void Vault
Zeph'gorog guards Nulgath's Vault and Library while the Archfiend is away. Appearing as the guide Zep, he helps Dage and the Hero find what they seek, then traps them to await Nulgath's judgment. After they escape and defeat him, Dage seals the guardian's soul in his own mask instead of destroying it.
