Adventurers needed to unrelease the ancient evil(s?) they unleashed.

Adventurers were hired by Sir Ser, Ra'ite Paladin, to cleanse either Ulashar, He Who Came Before Everything Else or Grognak, the Destroyer of worlds from the plane. The party went around Koth looking for Ulashar, before finding him. Half of the party sold their souls to Ulashar, before being cleansed by successful DI's to Vormaxia and Neptune, however, as a result of DI'ing to Neptune several times, Tobias was turned into a crab. The party sacrificed 1,000 innocents and bound him to Sir Ser's Superior Sunlight Greatsword, which became horribly tainted.
