During the Rage of Demons[as of when?], Erve went to an abandoned temple of Waukeen to take an inventory of the dead buried in the church's graveyard and crypt. However, some of the builders of the temple were secretly cultists of Graz'zt and their leader, by now a shadow demon, possessed Erve. Under demonic possession, Erve re-opened the temple as a sanctuary to Graz'zt. At last an adventuring party found and defeated the demon.
