201X. Why the "X"? That's because little Frisk wasn't quite the best at counting. And the calendar over their bed was about three years (five years?) too old. They DID know how old they were, though, and they didn't really have the tact to care about much else regarding numbers. Much less the number of people that weren't around anymore. Who knew how long ago it was now, but Frisk still remembered when the orphanage was filled with tons of other kids (most of which avoided them entirely.) Now, since the surface went through nuclear fallout, they were surprisingly one of the few people in the world to survive. Sure, they knew there had to be tons more, but still - when everyone who used to be around just stopped all at once, you really had to learn how to take care of yourself. And they did. One morning, while out on a supplies run, they must've made a wrong turn or something, because they ended up falling down a mountain. And apparently, monsters DO exist, and they're in a bit of trouble themselves. A disease called the "Black Mold" has broken out over the entirety of the Underground, killing off almost all of those unfortunate enough to catch it. Monsters are sick, dying, or long gone already, and nothing will ever be the same as it was before the illness contaminated the monster king, Asgore, leading to his untimely demise. With the cause (or cure) of the disease still unknown and highly contagious, along with no hierarchy left to lead what's left of the monster race, there's only so much a dying kingdom can do. However, Frisk's big heart finds a need to go and try to make things better for the monsters. Little do they know how sad, angry, and dead the Underground is, these days... Welcome to Devastale.
