Does anyone know anything about ancient Mongolian politics?

Hello! It is my first time using reddit and I don't know what I'm doing but I'm a writer and I'm DESPERATE. I'm trying to write a historically accurate(or accurate adjacent) sapphic historical fiction about the warrior princess Khutulun for my dear sister who has been begging for it and I need a minimum of 80k words but I know NOTHING about ancient Mongolia. 😭

I need info about nobility, combat protocols, weapons, weapon maintenance, clothing, social dynamics, food, etc. Anything helps really.
