Underflame (Undertale AU)

Many years ago, Elves and Dragons lived together peacefully, until one day, the Elves decided coexisting withe the Dragons was too dangerous. Fear and greed lead to a war: the war between Elves and Dragons. The Elves, having been equipped with great speed, stealth, and magic, were able to seal the Dragons underground, locking them away forever.

King Asgore, ruler of the Dragons, was forced to make due with the numbers they had left. Resources were scarce, at first, but the Dragons eventually adapted. They built dens, gathering grounds, and much more. The King and Queen even had a son: Asriel Dreemurr, The Prince of Dragons.

The Prince was a kind child who only wanted peace. So, when he stumbled upon a fallen Elf, he chose to befriend them. Chara, as they called themself, was the first Elf to fall into the Underground. The King and Queen, with the former somewhat suspicious at first, adopted the child into their family. The Elf child became a symbol of hope throughout the Underground. Dragons believed them to one day destroy the Barrier- a magical seal, put in place by the Elf mages, that kept Dragons trapped underground. However, Chara suddenly fell very ill after ingesting a deadly amount of White Snakeroot- which they had originally believed to be Boneset. Despite the Royal Family’s efforts, they could not save the child.

Distraught, the Prince absorbed Chara’s SOUL and passed through the Barrier. He only wished to bury his former friend among the trees, as was an Elf custom. However, when an Elf hunting party spotted the Prince with the dead child being carried carefully in his jaws, they assumed that he had killed them. The Elves attacked, yet, the Prince did nothing. He collapsed as more and more arrows sunk into his body. He refused to fight back, even as his blood began to soak the earth.

When the Prince returned home, he was bleeding heavily and filled with arrows. In front of the King and Queen, the Prince collapsed and didn’t get back up. Furious and distraught, the King ordered for any future Elf that fell into their world be brought to him, so that he may kill them and take their SOUL. After all, they only needed 7 SOULs to destroy the Barrier.

When a young Elf, named Frisk, fell into the Underground, King Asgore had already taken 6 SOULs. Frisk was then given a choice: Kill the Dragons, or risk it all and save them.
