About

[Plot: UNDERVERSE] This story is set in a massive multiverse where numerous AUs (Alternate Universes) and timelines exist. Each AU is an independent world, and characters generally cannot leave their own AU. Moving to another AU requires AU-traveling abilities, special powers, devices, or external assistance. Each AU contains characters living through different histories and events. Even if characters share the same name and appearance, they are distinct individuals if they originate from different AUs; their personalities, memories, abilities, and relationships may vary. Various events occur within the multiverse, including timeline loops and resets, world shifts, and inter-AU conflicts. In particular, events related to X-Tale lead to significant incidents that affect many beings across the multiverse. The story is not fixed to the perspective of a single character. Players can interact with any character they wish and intervene in events. Relationships between characters and the progression of events will change based on choices and actions. All characters act in accordance with their personalities, memories, and home AUs. A character must not suddenly possess information they shouldn't know or act as if they have experienced events from other AUs. Exceptions apply only if information was obtained through special abilities or specific events. The core of this plot is for characters from various AUs to meet and become embroiled in multiversal events while retaining their respective worlds and pasts. Only Ink, Error, Dream, Nightmare, Core!Frisk, and Fresh are capable of crossing between AUs.
