[THIS VERSION IS OUTDATED. I AM REWRITING IT.] Two worlds, so different yet so similar. Two evils from elsewhere, threatening to ruin the peace and content for their own selfish and sadistic desires. Get ready for some feels. I hope to have many in this story. I try to hold myself to at least 3,000 words per chapter. AUs involved: Swapfell, Underfell, Underswap, and Undertale. Cover art by yours truly.
