Bell finds an ancient artifact in the dungeon. The Hestia familia goes to the Loki familia to try to uncover what the artifact is. They gather in the meeting room. Bell and Aiz touch the artifact at the same time. There is a bright white flash so everyone closes their eyes. When they open their eyes again both Bell and Aiz are gone. Bell gets sent back to the past and ends up meeting Aiz parents. Aiz gets sent back to the past and ends up meeting Bell's parents; also the members of the Zeus and Hera familias.
This will be the last chapter until I come up with more ideas.
