...So all of this genocide is happening and no one of greater authority than the Dark Moon Clan is reacting fast enough to save even one family? The Azure feathers were the weakest of the families at one point. Are the Dark Moon Clan so large and prominent that they themselves can make up, at minimum, the labor output and trade influence of the people, the workforce, that they killed? As well, the reduction of standing army personnel that the kingdom requires to maintain its power overall?
The higher-up that was bribed must have to report these deaths to someone eventually, so you'd think he would be pissed enough to react considering he let the Azure Feather family live and basically OK'd the uprising, and is also likely holding on to Ye for the gems he's able to get his hands on.
