A Deltarune .Exe i thought of on a whim.
Design came before the lore, but here's some lore anyways:
- Malevolent extradimensional entity with no personality exists. Manifests in cyberspace. Prime Exe material.
- Attaches to a folder full of Ralsei-related files.
- The entity creates a fake personality based on the Ralsei files, intending to use it to lure in victims.
- Due to them not originally having a personality, the "fake" soon fills in the blanks.
- The new personality keeps their initial malevolence in check.
Also they're bigender
