In OuterDust, events unfolded as they did in countless Dusttale AUs. Sans was pushed through hundreds of brutal genocide routes, witnessing every friend and family member fall repeatedly. Eventually, his soul couldn’t take the torment. He snapped, slaughtering every monster in his path—even Papyrus. Now, driven by the desire to become stronger and filled with determination, he roams the stars, hoping to one day defeat the human who has haunted his existence.
