1. Right to rule: a variable that will decide how much would cost and how many of the clans could join you in a rebellion, or if you could be chosen as the next king, in the late game it could also be used to define if your kingdom would face a dynastic struggle if, for example, a noble family have an equal or higher quantity of right to rule than your heir, there would be a greater chance of civil war depending on mix of the clans leader traits and a pint of chance.
The right to rule could be earned through winnings battles, amassing good relations will the clans and (the fastest way) marring into the royal/imperial family.
2. Being able to assign tasks or general directives to your clans parties.
3. Dyeing the banners: Throw the power ranger's colour scheme in the pits of hell, make unifying the colours of soldier's equipment a paid option in the town menu, or limit it to shields, allow us to select clothing colours in the market menu as a paid option.
