The Disappearing City: A Tale of Family, Magic, and Redemption

One fateful night, the bustling city of Ebott vanishes without a trace. Only a handful of people-including Sans, his enthusiastic brother Papyrus, and the fierce warrior Undyne-witness the mysterious event. As panic spreads across the world, rumors of forbidden magic and lost timelines emerge. The truth points to one name: Doctor W.D. Gaster, the enigmatic scientist long thought to be lost to time.

Determined to restore the city, the trio embarks on a perilous journey through distorted realities and haunted voids, uncovering long-buried secrets. Along the way, Sans struggles with fragments of forgotten memories, leading to a shocking revelation-Gaster isn't just the architect of the city's disappearance; he is their father.

As the group confronts Gaster in his hidden lab, they must decide whether to fight him or trust him to undo his mistakes. But time itself is unraveling, and powerful forces seek to keep the city lost forever. In a final battle against magic and fate, Sans, Papyrus, and Undyne fight to reclaim their world-while Gaster searches for his own redemption.

When the dust settles and Ebott is restored, Gaster is no longer just a shadow of the past. For the first time in years, he returns home to Snowdin, where a new future awaits.
