At the time, humans and monsters ruled the earth. One day, humans attacked abruptly and mercilessly, out of fear of their only weakness, having their SOUL absorbed by a monster.Monsters were too weak to put up a fight; the soul of nearly every monster combined is only just as strong as the power of one human SOUL. Countless monsters were massacred, without a single human a single SOUL was taken, and countless monsters were turned to dust...Few monsters survived. Eventually, the monsters surrendered, and the humans emerged victoriously. The humans gathered seven of their best magicians and sealed the monsters under MountEbott with a magic of their greatest magicians we the ones to seal us… some of us put a spell on those magicians in anger and spell made it that the human descendants of the magicians ever two generations would have a terrible fate of falling down to the the war, the monsters retreated into the deepest part of the Underground, which would be called, Home."After a period had passed, fearing the humans no longer, they populated the rest of the Underground and settled their capital in a place they would call "New Home".Monsters mostly blamed the war on humanity and took a vengeful look on humans as a species. This bitterness, especially after the death of Asriel and his adopted sibling Chara, led King Asgore to declare war against humanity, installing a policy to kill all humans that fell into the Underground and eradicate humans once the seven SOUL's needed to break the barrier are collected. A monster with a human SOUL… will be a horrible beast with unfathomable are unbelievably strong. It would take the SOUL of nearly every monster... just to equal the power of a single human SOUL.
