Twenty-six years--that's how far into the hellscape that the Earth became Ethan survived. He'd become an old man in a world where even the young died by the millions. But those years were hardly the years he lived, as he simply struggled to survive. Untl, one day, a fairy-like creature he met by pure chance promised him something he thought impossible--a chance to redo his entire life post the Descent. Keeping the creature merely as a companion, with no hope of ever actually going back, he was that much more shocked when he opened his eyes and realised he was standing in the middle of his hometown, in front of his apartment building, precisely two days before the Descent--and before the entire world changed irrevocably and forever.  With a new chance, and a class cast in blood, he'll undo the things that broke him, and fulfill his end of the contract to become strong enough so that his against-all-reason redo wouldn't end up in yet another pointless tragedy. The world may become mad, but he had already become madder, and nobody will stand in the way of his goals--not the monsters that will come flooding the Earth, nor the people endowed with newfound magic and greed. All would be his, by will or force.
