The Blood

Thousands of years ago, Monsters preyed on Humankind. Humans feared going to bed at night for the threat of monsters waiting in the dark to devour them kept them awake and alert all night. Most Monsters were no more than primal, snarling beasts, the few smarter ones, were even worse, taking glee in the murdering of humans. This was until peace was restored, through the discovery of magic. No longer did humans need to die to provide food to Monsters, as magic provided it for them. Over the years, the Monster race grew and thrived, alongside Humanity, both culterally and physically. Despite this growth, the dark, primal urges of monsterkind lingered within them, dorment. Humankind were wary of this, believing that monsters could revert back to their old ways, if left unchecked, And thus became tales told to Human Children at night. Over time, tensions began to grow between Humans and Monsters. Humans were scared that monsters couldn't be trusted, and Monsters felt that Humankind has these beliefs founded in no evidence. As a failsafe, the greatest Human sorcerers placed a curse on Monsterkind. If they were to ever consume even a single drop of human blood, they would transform into horrific beasts. This, rightfully so, caused outrage between the two group, and for hundreds of years, this tension grew, until a full-fledged war broke out between Humans and Monsters. The rest is history.

These events slowly passed into the ages of time, forgotten by all, and as magic faded in humanity, so did their belief in monsters. Simmilarily, monsters no longer remembered the cuse placed upon them, swept to the ages of time

Soon after Asgore elected Alyphys to be the Royal Scientist, the detirmination experiments began. It was here in which it was discovered out of a sheer fluke, that human blood held traces of Soul energy. This discovery was brought forward to Asgore, and the Blood Program was kickstarted. The program was simple, if a human is killed, take their soul, and extract their blood. with this, they would have almost two souls worth of energy, meaning less humans would need to die, and ultimately, a faster path to the destruction of the barrier. Asgore nominated himself the test subject, believing that if there were any side effects, he deserved to be the one to suffer them, and not any other monster. Tings seemed ine to begin with, the only abnormality seemed to be that Asgore began to eat less, however, this seemed to not be of any signifigant threat. After this, things went swiftly downhill. Very soon, Asgore begane to constantly crave blood. He grew delerious, and violent, often having sperratic outbursts. His form started to change, growing rows of fangs and claws within a few hours after the symptoms first arose. The palace was evacuated, as he began to violently destroy everything in his path. Many monsters were bitten or hurtin the process, but other than that no monsters died. The palace was locked up, to prevent Asgore from escaping, where he was left to decay. After this horrid incident, Alphys went into hiding, and was not seen again until many years later. It was not realized that this beastly descent spread like a disease until it was too late. Pretty soon, many of the citizens hurt in Asgores' assault, began to change themselves, attacking everyone they came in contact with. Very quickly, New Home began to collapse, with evacuations happening in droves. The Royal Guard, lead by Undyne, arrived as soon as possible, to attempt to suppress the outbreak. They were quickly overwhelmed, and one by one, lost their minds too.
