Prologue:
Once Upon a Time

Once upon a time, in ages long past, there lived an age where two races ruled the Earth: Humans and Monsters. Despite both races' differences with one another, they lived in harmony together, working as one in order to ensure that the future held nothing but peace and prosperity for each race.

As time passed by, however, tension grew between both races as the ability of Monsters to take a Human Soul into their own and merge with it to grow incomparably powerful was brought into light. With this knowledge, fear as well as greed and envy were planted in humanity's hearts.

Heavy arguments ensued between both races regarding this information. Sometimes, it nearly came to blows which did not really help ease the growing tension. Until one day…

War finally broke out between the two races.

Nobody truly knows how the war started. This knowledge has been lost to History or perhaps, it was buried so deeply in order to prevent the present and future from finding out what has caused such strife between both races. However, regardless of the lost History, it can be agreed that the war has done nothing but widen the growing chasm between both races' relationship.

As the body count from the two races increased the longer the war went, so did the hatred, grief and fear in the hearts of every being in the land.

Monsters, as is common knowledge, are incredibly vulnerable to the negative intent of humans. With humanity having their actions backed and corrupted by their anger and fear, their killing intent has never been higher than before.

Despite the Monsters' magical prowess, they have been outnumbered by the many Humans whose souls and bodies were stronger than theirs. Their population has already been growing smaller from the long war. Outnumbered in both strength and numbers, the Monsters were defeated by the Humans.

Perhaps it was out of Mercy or perhaps it was even out of cruel enjoyment to watch an entire race suffer so much, it has been decreed that the Monsters will be thrown underground. The Monsters could do nothing but accept their fate. After all, how can they fight against an entire race filled with so much malice and killing intent? They would be wiped out in no time at all. The Monster King agreed to the decree, it was better to have been exiled rather than to have his entire kingdom killed.

The Monsters were exiled into the Underground and seven Human mages sealed them up behind a barrier. Cursed to never roam the lands and to see the sky again, the Monsters could do nothing else but make a home out of their prison.

And yet… Despite being imprisoned in a dark and dreary place, the Monsters continued on hoping with all of their hearts that someday, one day, they will be free again.

Day by day, the Monsters lived their dreary lives Underground, ruled by King Asgore who tried to create a kingdom that would continue on running and hoping despite their hopeless state. The Monsters kept their heads up, continuing to face the uncertain future head-on regardless of the lack of light at the end of that tunnel.

One day, a child had fallen into the Underground. The child had been found by their Prince Asriel who befriended the fallen child. They became a part of the Royal Family and created a strong bond of friendship with Asriel. The two children served as the hope of the future of the Monsterkind.

However, the human fell ill. The Monsters did not know how to cure the child of their sickness. As each day passed, the child's state grew worse until they died in their sleep one day. The Royal Family and the entirety of Monsterkind grieved the loss of one of their hopes but nobody took the loss as hard as Prince Asriel.

The child had made one last wish before they died; it was to see the golden flowers in their village. Prince Asriel absorbed his best friend's soul and crossed the barrier with their body. He carried the human's body into the sunset, back to the village of the humans where they originally lived. Prince Asriel had reached the center of the village where he found a bed of golden flowers.

He carried the human body into it, as they have wished. Suddenly, screams rang out. The villagers saw the prince carrying the human child's body and thought that he had killed them. They attacked him without any mercy. Yet, despite having the power to destroy them all, the prince did not fight back. Clutching the human, Asriel merely smiled and walked away.

Wounded, the prince stumbled home. He entered the castle and collapsed. His dust then spread across the garden. The entire kingdom was filled with despair. They had lost two of their brightest hopes in one night. Once again, the humans have taken everything away from them.

King Asgore, wracked with grief from the loss of his two children, declared that any human that falls into the Underground shall have their souls taken to break the barrier. It was time for the Monsters to finally come free of their prison.

As the years passed, six humans came and went into the Underground and each and every one of them fell in the Underground as well. Their souls were taken and stored as preparation for Monsterkind's freedom. The monsters now had six souls and their future was finally looking brighter once more. One more, they said, one more and soon we shall see the sky again.

The last human fell and he went through the Underground befriending every single Monster that he encountered, refusing to raise a hand against these beings regardless of how much they tried to take his soul. In a world where the rule of 'Kill or be Killed' reigned supreme, the last human had the mercy to spare the Monsters out of kindness. With his determination to save the Monsters from their fate in the Underground, he managed to break the barrier.

Finally, the Monsters were free from their dark prison.

Frisk Dreemurr, Monsterkind's hero and the adopted child of the royal family of the Monsters, became known as the Ambassador of the Monsters at a young age of thirteen. He had worked tirelessly throughout the past few years to ensure that the Monsters had the same rights as humans. He never stopped giving up the dream that someday Monsters will be able to live in the Surface peacefully and freely as a human being.

It has been eight years since the Monsters were freed. Eight years since the Barrier was broken.

A new chapter of their story is unfolding and things were sure to become more interesting soon.

This is the story of their lives in the Surface. This is the tale of their hopes and dreams.
