We put the campaign to bed with an everyone's here loot rush. The crew brought in a thing to blow up a bright age cache that all other factions were fighting over. They brought this thing along:
The Reconciler - temporarily disable the weak interaction, making matter fall in on itself through gravity and strong interaction. Stuff crumples in on itself. Which then leads to either black holes (if effect is long) or massive explosions (if effect is short).
