The Age of Worms
One of the quartet of Guardians of the Island of Last Resort, greeted the party upon their arrival (12 Fireseek CY 596, in Material Plane time) and informed the party that access to the Fountain of Dreams could only be gained by completing the Trials of Tilagos. He claims that drinking from the Fountain would free the lost Library of Last Resort, hidden away long ago by the Order of the Storm.
The party learned that Tylanthros and his three companions had actually sacrificed themselves to guarding the Island during a ritual performed by the Order of the Storm 1,500 years prior to the start of the campaign. After the party drank from the Fountain of Dreams, their work was finished and they were allowed to die. Before the ritual, Tylanthros had been the leader of the Order.
