Blackfiretale

The monsters have grown tired of staying down in the underground for so long, they needed something to happen. But one day they could have never prepared themselves for what was happening.

(An original undertale au by me called Blackfiretale)

Corrupted by a poison or mist, it was very hard for monsters to survive only leave few to live and then soon die.

Soon humans were there only hope for a cure, while humans in this au could destroy anything (like barriers) so everyone tried their best to kill the humans and the underground got more violent.

While that was happening echo flowers were the most important thing to everyone, even flowey.

Nobody kill me for using Gacha club!
