    Summary

    All you wanted was to live the rest of your life in peace and solitude out in the shadow of Mount Ebott. When you bump into the Prince of All Monsters, you find yourself unable to keep your nose out of trouble or be able to turn a blind eye to the atrocities that humanity is committing against monsters. Loneliness once meant safety to you...but you're beginning to realize that the relationships you've made are more important than the so-called-safety that loneliness provided you.

    Summary

    [CONTINUATION OF "THE MAD SCIENTIST OF EBOTT CITY"]

    After Asgore leads Ebott's monsters underground, Queen of Ebott, Leofflaed, is left widowed and defenseless against Captain Asher and his monster-hating army.

    Chased from her Kingdom for her sympathy for the enemy, only to fall into the hands of another King and his dubious ways, it appears there is no rest for this lost Queen.

    But perhaps there is a brighter side to it all, held within the smiles and giggles of an innocent Prince.

    Summary

    To magic, intent is everything.

    It dictates if a monster lives or dies on their own accord, it tells if a human is or isn't able to idolize their own magic to the fullest. The strong-willed amongst both of those can do the unthinkable, if only they truly want to.

    Seven Mages are poised at the foot of Mount Ebbot to put an end to a dying war.

    — but one refused.

    Summary

    Far away and long ago, two races ruled over Earth, Humans, and Monsters. However, why is it that when all was at peace the races began to stir conflict out of nowhere?

    (F/n) has always been bad luck and to be frank, was never more than a pawn into someone else's game. When you think you've finally bested your inner demons they conquer your mind once more, caging you to the decision to either fight against your own race or fight against the family that never stopped believing in you.

    Summary

    Monster were freed by Frisk the human, who had disappeared after the barrier broke 25 years ago. No one knows where Frisk went. They soon be came a legend.

    A few years later, Toriel died from an assassination, poison to be more accurate, 11 years after Monster where were freed from the Underground. Asgore declared war on humans, almost whipping them out. From 80 million humans soon became seven-hundred. Asgore was wounded in battle, and was soon killed the same way Toriel did, by poison. Asgore's dust was buried next to Toriel's, at the start of the underground.

    No one became the king. Instead, Monsters adopted the same things humans once had. (Presidents and stuff like that). If a hostile human was found, they were killed on the spot.

    14 years later, Sans went back to the Underground to get something from his old lab, that was beside his and Papyrus's old house. As he was about to head back he saw someone he hadn't seen for a long time.

    Flowey.

    Sans, curious, followed Flowey back to the start of the underground. Where he found a hooded person watering the flowers that sat on the royal family's graves.

    That's where this story begins-

    Explores multiple potential universe setups and--get this--two bitter assholes being blindsided by the power of friendship. Will probably break your computer if you don't click 'chapter by chapter.'

    Summary

    It had been a month since the barrier on Mount Ebott fell, and the monsters returned to the surface. Since then there had been protests and rallies, enough news coverage to make even the best reporter’s head spin, and government conferences discussing the new laws that would have to be put in place. Many people were displeased with the monsters return, and some were filled with excitement and curiosity. No matter which side a person fell on, they all had one thing in common; no one had expected the monsters’ arrival. No one even knew they were down there. The knowledge of their existence had died out centuries ago, and the humans capable of magic, the ones who would have carried that knowledge, had all but disappeared. The humans, mages, and witches who had fought in the war that put them there were long since deceased. All except one.

    Summary

    War, as Death's herald, is a strange and wondrous thing. In its own unique deleterious way it is both judge and jury, passing sentences unto all regardless of creed or privilege. Like a disease for which there is no cure, it spreads unchecked and spares none terror, grief, and despair without equal.

    Might it be possible for this, a catalyst of destruction, to unify? To deepen bonds?

    Herein lies twin tales of kinship among four distinct souls, forged by trials and tribulations of mortal coil.

    Summary

    England's monster King, Spades, is convinced to move underground by his lead Knight after feeling a powerful aura arising to the surface from a mysterious source. Many monsters were not too fond of the idea to leave the light of the sun for the dark musty underground, and stayed behind instead.

    When the Monster-Human war ended, the once-Lightner monsters were pushed down with the Darkners. Not everyone was pleased with the situation. 4 Kings, and millions of civillians searching for someone to look up to. With the fountains irradiating that toxic euphoria, it seemed as if everyone was going mad as each day passed.

    But, as long as you have someone to confide in, would that really matter anyway?

    Even if you're losing your mind?

    (A history on the Darkners, how they tie to Undertale's timeline, a backstory on Jevil's friendship with Seam and the cause of the jester's madness.)
    (This can be read as either shipped or not.)

    Summary

    11th Century A.D or so, in Ebott, Germany:

    Dominik Vogel was a well-known doctor. High success rates were in his reputation. Humans and Monsters alike sought his help. Vogel, however, had other interests.

    Ebott was a split kingdom. Monster's generally stuck to the far east of the mountain with their Monarchs, and the Humans stayed west, with their respective rulers. Neither were too fond of each others company. There was constant fighting on the kingdom's streets.

    Vogel wanted to change that. For worse.

    Meddling in dark magic and practicing his foreign skills, it would seem there is no hope for this estranged doctor.

    But Asgore hasn't given up yet.
