Ah hello! Not really an ask but I thought I could help clarify a bit on what happens to some magi characters. There's no specification where they are exactly. But it has been stated in chapter 280 for being part of the rebel (western) army in the Kou civil war, Kouen's household and Chuu'un are imprisoned as consequence. Hopefully that helped clarify things a bit! Unless you just wanted an exact location then it's a mystery to me as well..
