Ixys Engine Rooms

Board

(One of) the Engine Rooms powering the floating wizard-city of Ixys. Whenever wizards are banished form the city, the majority of their powers are stripped and fed to the engines, which also harness the ambient magical energy of the world. This map consists of a main arena and four branching rooms, each of which contain a spire within with a killswitch at the top. Do your players need to disable all four towers to move on? How will they get to the switches, and is there something waiting for them in the arena?
