When a student of Southside High encounters an unexplained phenomenon. Who do they call? Dacio Thalassa, the eccentric President of the school’s paranormal club. What starts as a mystery in an apartment leads to a mass kidnapping, a trip into the labyrinth of buildings that have sunken into the Southside sewer system and a cult attempting to wake their otherworldly master with her blood! Attempting to discern the cult’s interest in her leads Dacio to North End and the life she ran away from. Her reluctance to return north of the river is validated when she learns of the brewing conflict within the city. A conflict that has her closest friends and bitter enemies on both sides. A conflict that can only be resolved by Dacio, the last oracle of House Thalassa, choosing a side to support. But Dacio’s vision, the one she’s tried so hard to avoid, is starting to come true. Will her choice be the bridge that brings the city together or the spark that tears it apart? The end of the Fourth Age begins on the night of the Convocation.
