Part 1 Act 1: Before the Fall

Years after mages are exiled with a warning that any of their descendants found will be executed, Kokoro wanders away from their village and is captured. A witch trial is held, leading to them being carried and thrown down Mt. Mauga. Kokoro falls near the throne room of Tacarmi Castle.

Part 1 Act 2: Taken Prisoner

Unable to move, Kokoro is found by guards who take them prisoner and bring them before the Royal Family. Fearing the damage a human could do, King Drazalor has them locked away. Prince Torben and Dr. Dagger take this opportunity to study the human and eventually they develop a friendship.

Part 1 Act 3: New Family

Months go by until with the Queen's and Prince's convincing, Kokoro is let free to live with the Tacarmi Royal Family. Somewhere along the way, Kokoro and Torben make a plan to get revenge on the surface, leading to a similar plan to canon UT. Torben absorbs Kokoro's SOUL, they pass through the Barrier, rampage on surface, retreat underground, and die.

Old Part 1:

A child, by the name of Kokoro, was thrown down the mountain. For unknown reasons, they were considered a demon by their fellow humans. The fallen child was soon captured by the royal family. After months of confinement, the prince, Torben, soon after absorbed Kokoro's SOUL by accident. With their newfound power, they crossed over to the surface world. When they reached the surface, they both begin to rampage on the surface. Underestimating the humans, they were both incapacitated.

Part 2: The Aftermath

Nothing good can come of this.
