Undertale Wildfire is a fan-made prequel to Toby Fox’s Undertale, centered around the second fallen human: the soul of bravery.

"There is a human living in the furthest reaches of Snowdin. Riley builds a new life in the Underground piece by piece: the cabin has light, the pantry is stocked, and their hat helps them blend in at the village."

"None of the monsters suspect a thing… except one."

"When the mysterious and powerful Mr. Sunshine attacks Riley at their isolated cabin home, the human is left with overwhelming fear from his vicious assault."

"Sunshine's parting demand is simple: confront him in the capital."

"Join Riley on their search for courage through never-before-seen parts of the Underground: the remote tundras of Snowdown, Hotland University, the streets of New Home, and more."
