Summary
Sans has finally managed to fix the reset issue. It only required the deletion of a vital character. The barrier is broken, and time finally begins to move again. Recovery is slow, but Sans finds solace in his dreams. By the time he realizes his dreams of other universes are real, he has already grown attached to their residents. And then he's attacked at home and is thrust into the multiverse proper. He finds things very different from how he expected. His old friends don't recognize him, and some of them appear suspiciously older.
It doesn't take long before Sans starts to suspect that he may have a larger role in the multiverse than he predicted.
I wanted more Classic adventures through the multiverse, so here's my contribution. And cause I'm me, I can't help but try to make a saga out of it.
Features Classic being Classic, strange multiversal mechanics, and a sleep-deprived author who 100% knows what they are doing
