    Summary

    Basically my own Ideal interpretation of underfell, with some things here and there being changed, while others remain the same, it follows the story and what not, from the perspective of the protagonist like in undertale.

    Summary

    It's been over 50 years since the start of the turf war. Ever since the monsters and humans attempted to co-exist with each other all of those years ago, fierce and intense conflicts started to rise between the two races. Even after all this time, the war still continues to rage on.

    The notorious "Skelebrothers", Papyrus and Sans have risen to prominence during this period of time, and are now two of the most feared--and hated--pair of monsters to ever walk the monster cities' cold, unforgiving grounds.

    The story that you are about to read revolves around the eldest Skelebrother, Sans the Skeleton, as he uncovers the untold, dark secrets of his past, the reasons as to why neither brother is able to remember where they come from nor why this intense war broke out in the first place, and the discovery of a deep, twisted romance brewing between the two skeletons.

    Welcome to the cruel world of "Bones n' Blood."

    Summary

    After a very bad, life-threatening accident, Basil finds himself waking up at the bottom of a hole. He was shockingly trapped inside a large, secluded region under the surface of the Earth, separated by a some sort of barrier. The In-between. When a human falls into the In-between, it means they have given up their soul. There was probably a thousand reasons why Basil might have given up his soul – too many for him to count on one hand but his first thought was guilt. Guilt over what he did to Mari, and not understanding why he did it. Guilt over he tried to stop Sunny from leaving and living his life.

    Now Basil has to deal with monsters trying to steal the little soul he has left, a deranged talking Sunflower that keeps popping up and mocking him…but mainly…he has to deal with this black and white Sunny-look alike that just won’t leave him alone – A Sunny-look alike that won’t take no for an answer…

    Secrets, heartbreak, betrayal, will Basil ever be able to rest? His mind had already been broken – this was the last thing he needed.
