Who Are The Key Factions In The Space War In 'Library Of Void'?

Okay, so the factions in a multiversal war are where the concept really sings or flops, honestly. The easiest mistake is to just have them be direct analogs of Earth nations but with spaceships or magic—if I see another 'Galactic Empire' versus 'Rebel Alliance' but they call it the 'Celestial Imperium' and the 'Spark Resistance,' I'm out. The key is making the conflict ideological or existential, not just territorial. I think about something like 'The Locked Tomb' series, where the factions are built around necromantic lineages and theological dogma—it’s not just who fights whom, but why they can even perceive reality differently. For a war across realities, you need factions whose very existence contradicts each other. Maybe one faction wants to merge all timelines into a single, stable 'Prime' universe for order, while another believes in perpetual, chaotic branching as the natural state of consciousness. A third might be pure archivists, trying to record every dying timeline before it winks out, and they'll weaponize history itself. You also need the wild-card factions that aren't fighting the war but exploiting it. Dimension-hopping mercenaries, reality-smuggling cartels, or even conceptual entities that feed on the conflict—like beings that grow stronger from the entropy of collapsing universes. They add layers that prevent it from being a simple binary. The conflict should feel so vast that no single faction has a full map of it, and loyalties shift based on which reality you're currently standing in. Ultimately, the most engaging factions aren't just armies; they are civilizations with incompatible truths. The war isn't over land but over the right to define what 'real' even means. That’s when the stakes stop being about who wins a battle and start being about which version of everything gets to keep existing.
