Collapse Eternity/Implosion Infinity

When the Big Guy–Creator–and his consort Oblivion begat Chaos and Cosmos they imbued the twins with infinite power so they could create a Multiverse to their whims.
However, Cosmos did not play fair with his sister Chaos for which she became unreconcilable to the fate her brother forced upon her. In retaliation she began the process to destroy all matter and energy before ending eternity and infinity for all time.
