How do I find taen for the last battle with him

General Discussion Questions

I talked to Orion and that girl you battle in the perfection cult base where do I go now?

Head to Gaea Town and enter the First Augur’s Gym in order to access No Man’s Land.

Btw that isn’t the last battle, after you fight him there, go heal at the pokemon center and it’ll say something about taen going to the Utira library. Head there and you’ll find Orion and the dude you met with the zygarde. They’ll say about taen going to the dragon ruins so head over there for the final battle against him
