I think this is mostly kind of a PTSD thing. In the shattering of the might of the House legions against the Bull, Tepet Arada has foreseen the fall of the Dragonblooded Hegemony, and now just gets drunk and rambles about how futile it all is, while the family can only try to keep him out of sight because nobody wants their crazy uncle spouting heresies like "the Dragonblooded won't rule the world forever"



See, I think this works because it sounds like it's not anything formally agreed upon. On paper, the satrapies are still Tepet's, Sesus and the other Houses...
