Underspiral | An Undertale AU

The Spiral Timeline (S-Timeline) is a bit odd. Monsters are sealed in the underground, like any other timeline, but instead of monsters biologically having magic, the humans are the ones that biologically have it. Instead, monsters use a type of energy called Autospiral.

How it works -Autospiral is an artificial form of magic, originally made of a compound extracted from Echo Flowers, found by Royal Scientist W.D Gaster, who’s been gone for years. -When used, Autospiral forms sigils on the user’s hands. The “magic” formed by this, as well as the design of the sigil, is based on the type of monster someone is, as well as their history. -Humans are able to use Autospiral as well, although less effectively, as it is made for primarily monsters. The sigils formed when a human uses Autospiral are still based on their history, however are yellow instead of the usual blue.

Backstory -You know how it goes. Humans and monsters rule over earth. War breaks out, monsters end up underground. Only in this timeline, it’s different. Humans are the one with magic instead of monsters. Doctor W.D. Gaster was working on an artificial form of magic (Autospiral). Unfortunately, an unfortunate early test of the substance caused his death, leaving his assistant, Alphys, to pick up where he left off, eventually perfecting the substance.

-Fast forward a few years after the war to 201X, a human falls down… or is it two? Whatever. As the human traverses through the Underground, they don’t really interact with anyone. However, there are differences at times. Different hairstyle here. Different sweater there. Eventually, they realize they can’t leave the Underground, and decide to settle down in Snowdin, living there for the rest of their life.

Characters -Frisk/Chara: Instead of being two separate people, they actually share a body. However, there’s a few differences when the person in control of the body changes, such as the clothes and hair. Frisk wears a blue sweater with two purple stripes, shorts, and leggings. Chara wears a green sweater with one yellow stripe, and cargo pants. Frisk doesn’t know how Chara got there. She kinda just… appeared in their head one day. However, when they swap, their clothes and hair change as well. Chara’s hair is shoulder length, meanwhile Frisk’s is longer and more unkept. After the swap, Frisk can manifest as a ghost next to Chara, and vice versa. However, only they can see each other. Frisk is a lot quieter, however Chara talks a LOT. They’ve lived in the underground since they were a child, and are an adult now.

-Toriel: A goat monster who is the caretaker of the Ruins. She’s HIGHLY opposed to using Autospiral, as she doesn’t think it’s ethical. She’s very nice though, and will assist monsters who ask for it. She also likes baking.

-Sans: One of Snowdin’s two skeleton monsters who lives with his brother, Papyrus. He doesn’t mind using Autospiral, but he prefers to use regular weapons, unlike Papyrus. He’s not the most talkative, however he does crack jokes sometimes.

-Papyrus: A skeleton monster, and Sans’ brother who lives in Snowdin with him. He trains with Undyne, wanting to become a Royal Guard. Using Autospiral is what he prefers to do in combat. He also loves cooking and making puzzles, and also loves hearing feedback. He hates the jokes that Sans makes.

-Alphys: A lizard monster. She’s also Underground’s Royal Scientist. She isn’t really shy, but just doesn’t like talking to people at all. She took over in Gaster’s place after he died.

-Undyne: A fish monster. She’s the head of the Royal Guard, and she’s also really loud. She trained under Asgore as a kid, growing up never being able to land a hit on him until she finally managed to get one hit on him. She trains Papyrus, but thinks he’s too nice to join the Royal Guard.

-Mettaton: A ghost who possesses a robot body that was made by Alphys. He performs for the Underground. His weapon of choice is a staff that uses Autospiral.

-Asgore: A goat monster and the king of the Underground. He was the one who originally endorsed Gaster’s research, and was devastated when he found out about his death, promptly named the Echo Incident. After his son Asriel’s death at the hand of the humans, Asgore was hellbent on collecting human souls up until he collected the third one, ending up only wanting peace. He lives alone in the capital, due to his wife, Toriel, leaving to the ruins.
