    Summary

    What the title says. Concept for an “swapfell” or “fellswap” au that isn’t actually Swap or Fell.

    In the sense that it isn’t the same cookie cutter personalities and lore every one of those AUs seems to have. Not everyone is an edgelord either.

    (NOT saying I dislike Fell or Swap aus. Some of them are really good. Mainly dislike fanon centric underswap personalities)
