The records tell us that the Otherlords broke into our reality, our space/time continuum, from somewhere else, from “Outside”. To those who saw them and lived, they appeared as moon-sized maelstroms of roiling energy and matter, and wherever they encountered life – or even the potential for life – they annihilated it. They scoured planets down to the bedrock, leaving only the bones and grave-dust of corrupt, contaminated worlds.
And yet, in crossing from their dimension into ours, the Otherlords in fact put themselves at a disadvantage. As immense and powerful as they were, they made themselves subject to the laws of our universe when they entered it.
Under the lash of imminent extinction, humanity created and deployed weapons of horrifying power and scope. Sun-lances that generated CMEs from a system primary star, then focused them like a laser. Singularity cannons that lobbed artificial black holes. And the worst – dark antimatter.
But these – and more – were used at a cost. Sun-lances left stars dangerously unstable; singularity cannons twisted the very fabric of space/time, and dark anti-matter weapons left a lingering taint, a contamination not unlike that of the Otherlords themselves. Fighting fire with fire, perhaps.
Bit by bit, the invaders were destroyed or pushed back to their origin point, an otherwise unremarkable mass point drifting in the void. If they expected to find a way out of our universe, back to their home, they were disappointed. Their doorway had closed. They were pummeled into memory.
