Find the Tender of the Waters in the north tower and use the Empty Vial to receive the {[riftitem|quest|Vial of Blessed Water}}.
Use the travel Shard in the same tower to teleport to the Temple Seat. Anoint the body and light the incense. No surprise, this does not go well. Jace is frightened, saying "I will not be taken again!" and he attacks. Anthousa Mona and Ieros both join the fight but they cannot hold him. Anthousa entreats Ieros to do something and he agrees. Jace screams one last time, and he and Ieros both vanish.
