This fic will span over many years, following the Marauders through all seven of their Hogwarts years and into the subsequent three years of the First War, concluding with the events of Halloween 1981. The main focus will be on Remus, Sirius, James, and Regulus w/ most chapters told from one of their POVs. It's pretty slowburn and also looks like it's going to be pretty long, we're talking 100+ chapters.

A Very Non-Magical James Potter from 2022 and a Very Magical James Potter from 1979 accidentally swap universes, and now must figure out how to get back to their own worlds. Oh, and Regulus Black is inextricably involved in both universes, which is obviously just a coincidence.
