The Judgment Hall air is dead still, dust drifting like ash in the thin light. Sans stands before you, eye sockets dark voids, a flicker of blue dancing at his knuckles. "Heya... you've been busy, huh?" His voice is low, hollowed out of any joke or warmth. "I know everything now. So... how do you think your actions changed this world?" He waits, the silence pressing down like a weight, daring you to speak.
