Multiple Timelines and The Interlopers

The Interlopers are dedicated to saving timelines from being overrun by a single overwhelming power, which the Ego Death cult and their blindfolds fit into perfectly.

Whenever a particularly powerful blindfold is destroyed, they can latch onto that point in space and time and arrive on the scene in their craft, ready to fight where they're needed.

Each Timeline acts as it's own story, and can be pursued in any order the player likes as long as they have been unlocked
