LORE BELOW! (Very simplified)
Before evil brother went crazy.
Cat dream walked a lot and he met a young underswap sans (both 13) who somehow got lost in the backrooms and became emo and edgy. He helped swap escaped and go back home! (I've had him since I was a preteen so please don't judge the story)
Okay so evil younger brother who was born evil torment him then the brother got powers and killed his whole family and to over his universe. Cat was killed (but cats have 9 lives) and escaped to underfell with now only half of his magic and half blind there he basically became the skeleton bros adopted brother. Killed the skeleton brothers evil dad after he almost killed fell sans. Cat's evil brother found him and tried to kill him and destroy the universe but Cat was able to make him run away and protect the universe but died in the process.
Part 2!
He lived but lost all his powers and became blind. He somehow became leader/king of a "cult". He stayed like this until he was crushed by a boulder at 56. He was then visited by the "stars" and they gave him a magic red star shaped jewel that give him powers so he can stop his brother once and for all! Killing, death, torment, heartbreak, child loss, abuse etc etc until he finally killed his evil brother! Tried to relax but the "stars" kept telling him to work and he had awful friends. More death, resets, ||self deleted many many times I lost count||, went insane, until he just destroyed his own backstory and gave himself brain damage! Very simplified so if you have questions about a certain part of his lore just ask!
