Summary
OC MC. OC x Ahsoka. OC POV mostly. This is a huge multi crossover from an ai dungeon playthrough. Edited of course. Several factions find themselves on The Liminal Nexus, a forerunner shield world that connects the multiverse. The Main Antagonist is the banished, the Didact, the flood, and The Witch Cult, though there are others. The POV is mostly Bubba the OC but eventually I found out how to do other POVs in the ai dungeon game, much later. The characters are shown on a bit of a rotating basis through the MCs POV. While the story itself generaly rotates between issue, talks, fighting and ealing with issue, resolution, downtime, training, issue, repeat.
Trauma, relationships, Sci-Fi, action adventure, huge cast, therapy, big battles, sparring, ship combat, found family.Series
