Here is my idea: New Nightborne ruler title names. The duchy and county title names could be rename. Instead of the generic "Minor Lord" sort of titles maybe something such as "Minor Arcanist" or "Chief Arcanist" for Duchy level title rulers. Or even a unique not so lore friendly title like "Grand Mage/Magus". Elisande (The Nightborne Leader at start) appears to be the only one with an interesting ruler title. And if the Nightborne are updated then perhaps the Highborne could get some titles as well.

@Agnu
Take it in the to-do list. Btw, next update, including new nightborne titulture, reworked cities, new necrarchy titulature and minor human, orcish and mogu rework will be released after main mod will update
