I haven't finished any of the lore yet, but here's a quick summary. Basically called on a called a god, who said that they can help Sans defeat the human for good. After losing all his hope of trying to defeat the human, he made the deal with the god. The deal was Sans had to somehow the human's soul, and then give it to the god. By giving the soul to the god, Sans would be gifted with enough power to finally stop the human. But after the giving the human's soul to the god, the god used the soul's Determination to completely change the timeline. Turning the Sans into Sano and making go down the same path as Sans. Killing everyone to get stronger. And that's all I have for lore right now. I might turn this into a fangame, but I don't really know. always byebye. ._.
