As new recruits to the Time Variance Authority, your day-to-day is pretty straightforward. Catch a case from the Judges, put together an insertion plan, dive into the Multiverse, resolve the incursion, and return home. While you visit other realities, you're never truly part of any of them. As such, it's vital to monitor your health and well-being as a permanent inhabitant of the Null-Time Zone.

The Lacuna game system facilities these stories by presenting the players with characters who are part of one world but visit another dimension. The mechanics tell the story of outsiders to a reality wholly unlike their own. In the beginning, this system serves our purposes perfectly.

Then, it happens. The characters become something more than a typical TVA employee. The core mandate of the TVA is laid bare before them, and the truth behind the truth is revealed. Their fate moves beyond that of their peers and into a place where the very nature of the multiverse is revealed to them. No loner outsiders, the characters now truly inhabit the dimensions and realities they visit. Everything changes.

The Flux game "system" helps bridge the gap from Lacuna to the systems beyond. Not a full game unto itself, but a tool for managing characters who live lives in more than one reality at a time. With these mechanics come new stories of how the multiverse reacts to the very presence of these characters.

With the truth of the TVA and reality revealed to the characters, the story moves into the late game phase. Just because the characters understand doesn't mean the multiverse is any safer than it was before. The difference is now the characters are in charge of where they go, what they do, and what incursions they battle.

There is no set game system for this section of the game. Because of the usage of Flux, the options are nigh limitless as the characters hop from reality to reality. The stories told in this section are highly dependant on the system used.
