Outland Warriors

Aether and Paimon were in the middle of a tough fight with Ruin Guards when they are transported to another world, far different than the world in which Teyvat resides.

Aether and Paimon awake to find a strange group of people. A strange group of people gathered to help save a kingdom from destruction from monsters from another world. It takes another twist when it turns out several members of the group were also transported from other worlds.

As they journey, they meet more warriors from other worlds, gathered by fate to save the kingdom of Aytolis from a certain demise. Aether and Paimon are also joined by several of the adepti, and a certain wine loving archon, who were sent from Teyvat to random places throughout the kingdom.

I've taken some creative liberty with this and added characters, and made a few other changes for plot.
