i know here is not a history discussion topic but because Mstislav is one of the playable characters in the game i thought perhaps some one can help me with this.
Mstislav was one of the few surviviors of battle of kalka river.after the battle ,according wikipedia:Mstislav reigned in Halych until 1227, when boyar intrigues constrained him to leave the city to his son-in-law, Andrew of Hungary. Thereupon he retired to Torchesk, where he died in 1228.
where can i find some info about his later life in torchesk and whether he still had power in toerchesk or not?

He reigned there too, but took the vows of schema (strictest monastic rule) before his death.

thanks for the info,btw,i think making a game about him and his father is interesting, or perhaps Daniel of Galicia.he also had important role in history (more than Mstislav).
