Defense of Scadrial Week 1/?

Party was sent to the plane of Scadrial to stop a group known as the Ire. They investigate an old base, left obviously in a hurry, and found something known as a Seon and papers referring to a Canton of Inquisition. They investigate the town and found the building, but don't get further. That night party discovers the mist, which is the body of a god, covering the town and presumably planet. Van and Semiramis receive a voice in their head from "Hoid".
