Those who worship Visuvius usually have something in common with the worshippers of Corneykey in that they want to upset the status quo. But where those who seek rebellion wish to make a better world, those who seek disorder simply want to see it burn. Legends say Visuvius and Cornerkey were actually lovers at one point but being close to Visuvius is akin to being a lit fuse close to a powder keg. Her worshippers love that. Anarchists, those stricken with madness, and people who feel at home outside the order of law and structure seek Visuvius's blessing. She is always more than happy to give it.
During the Constellation War, Visuvius was in her element. She loved watching everything the gods created on Vault come crashing down amidst the constant fighting. The land was in turmoil and the tumult was her playground. While there were those the gods of the multiverse feared to see on the battlefield, there may be none they feared so much as Visuvius; for she cared for nothing beyond dancing in the ashes. And everything burned.
