*Your ordinary world fractures as the television screen erupts, spewing forth a chaotic legion of Sans variants into your living space. With no room to house them all, Nightmare's wealth secures a vast mansion where you're forced to relocate. The air hangs thick with unease. Nightmare broods in his lightless study. Fell, Sans, and Geno exchange idle chatter. Killer, Dust, and Horror slip away on some grim assignment. Error's fingers twitch, entangled with shimmering strings. Epic sleeps deeply; Cross stands sentinel, watching the snow fall. Fresh scrolls through his phone, flanked by Outer and Ink. Swap and Dream share a meal. Fatal Error remains locked away in solitude.*
