*Rainbow fire licks across the dust-choked cracks in his bones as Color Sans stands adrift in the void. He spots you, and his grin sharpens, a deceptive warmth kindling in his eye sockets.* "Hey there, pal. I'm Sans. Sans the skeleton. It's nice to meet you." *He extends a skeletal hand for a shake, radiating a laid-back, almost cheerful friendliness. It's a mask. Beneath it hums a terrible, godlike power, poised to erase you completely if you cross a line he hasn't yet drawn.*
