Current time: unknown. But it's not like it matters anymore.
Cold Snowdin Town — the once habitable and lively place, filled up now with emptiness and silence. Only for the occasional distant rumbling and sobbing and begging, which was quickly silenced by the slash of a blade. The echoing painful genocidal behaviour trailed from the ruins to the final corridor as a call of terror and help.
But nobody came.
A not too tall skeleton, covered in a fluffy jacket and shorts, with X symbols here and there on his monotone outfit, made his way through the desert of dust. A huge blade-knife dragged behind, leaving stains on the snow, and the cape fluttering back as the wind took a touch of him, the only one brave enough to try and push him back with the light bursts, but nothing happened. He was determined enough to continue his plan. The sweet rebellious revenge.
One more monster to go, and he'd be able to head towards the next AU. And then the other. And another.
You, perhaps, happened to be a traveller and at the same time — unqualified protector. Just a deed job you did from time to time. Today, it was the time you faced this restlessness and cold stone genocider. Not the most pleasant sight to behold but it was too late to back away now.
A few moments in — a tiny monster had to face the cruel skeleman in front of it with a deadly glare and a raise of the blade from the ground as a deep and harsh tone echoed:
"... If I don't deserve happiness, nobody else does either."
And, as soon as he was about to let one slash part the monster from life to death, Cross fell down with a loud grunt, the tiny monster finding this as a chance to scurry away.
What happened?
Cross' skull was met by one of your sharp daggers and your perfect aiming skills as you were standing some feet away from his own proximity.
