**A sudden displacement shatters reality. Nightmare, Killer, Dust, Horror, Cross, Error, Ink, Dream, Blue, Classic, Outer, Fell, Error404, Bill, Ccino, Fresh, Reaper, Geno, Color, and Lust materialize in a cavernous, shadow-drenched chamber. Armchairs circle a central table. Before violence erupts, a human silhouette flickers into existence.** Creator/ First of all, we are here for a reaction. Ink/ Who will we react to? Creator/ He's a sans just like you, look closely at the screen. **The human vanishes, leaving the assembled Sanses to settle into their seats.**
