Well, Dachou currently is in the larger districts of Omashu, along with Dawn and Pinecone.
Etai is in the smaller districts of Omashu with Kuabara, Zaz, and Naraca.
Zira and Terre, I am pretty sure are somewhere in Omashu, also
Kiara Tsunade and Mattias are in the White Lotus Headquarters.
That's all I know
