Earthward Bound The Worst is Yet to Come

  If life was a game then Rodinians long ago mastered it.
  Survival and the dangers of the universe are mere distant hypotheticals they need not worry about. With near godlike and unmatchable capability and power, they know of little hardship or suffering, no anxiety or urgency, and no threats or hostilities; only a suicidal lunatic or a fool would challenge them. Yet, with all their power, they resign themselves to passivity and non-interaction with the rest of the cosmos, under a strict doctrine of non-intervention. But if this doctrine were iron-clad and eternal, then that would be the end of it. But it's not, and as such there are serious consequences for the rest of the universe from the existence of such godlike creatures.

When two relatively young Rodinians, Quixos Thezumai and Kalrinasqua, are confronted by the hardships faced by those not lucky enough to be a Rodinian however, they find it difficult to accept or obey Rodinia's doctrine. The stark contrast between their lives and the lives of those outside Rodinia brings them into direct conflict with those non-interventionist laws.
  With the aid of a rebellious Rodinian Mycoship called the Quellor, they break contact with Rodinia and join the free Rodinian enclaves hiding throughout the cosmos, intent on delivering some good luck to those less fortunate than themselves. As the centuries tick past however, a wedge develops between them concerning how far they should go in their mission to make the universe a better place, and for how long in the face of enormous cosmological scale and the impending end of space-time in only 21 million years. But if Rodinians running rogue to provide aid and happiness were the only ramifications of their power, then the universe could breathe easy, and perhaps wish for one day when Rodinian non-intervention ended.

That is not the case. Rodinia was originally meant to be the guarantor of all rights; the unbeatable guardians of innocence and justice. It was never meant for Rodinia to fall into tyranny itself. But what if it did? The repercussions for every other civilization in the cosmos would be of existential concern. Supremacist political forces begin shifting the once ossified and immobile tectonics of Rodinian politics towards a ghastly outcome, exploiting the end of the cosmos as a political crutch to seize power. Their success would undo all the good deeds of the enclave Rodinians-in-exile, and spell certain doom for all non-Rodinians.

Meanwhile far out in deep space, with Rodinia's gaze turned inwardly and those few Rodinians-in-exile stretched into near irrelevance, something reawakens unnoticed. It's vengeful eye glares at Rodinia with long imagined revenge, but its mind ponders an even worse atrocity that would stun the universe into silence. And something else, still, descends on our universe; something the Rodinians with all their godlike power and intellects cannot fight or explain. Whatever lies ahead, be it mortal suffering, supremacist politics, or godly revenge, the worst is yet to come.

  And whatever it may be, our universe's only way to resist are the Rodinians. A civilization of deeply flawed creatures, whose brains evolved not to handle godlike power, responsibility, or the capacity to think as a god, but instead had godlike power and responsibility thrust upon a brain designed for little more than chasing prey through primordial lands and oceans of Earth, with all the flaws therein.
