Impact of Faction Leader Traits/Retinue

[Goofball]

Do the faction leader's traits/retinue impact the empire as a whole, or just any particular city he happens to be the governor of?

For example, if my faction leader has a spice merchant in his retinue, does the entire empire get a bonus on trade income, or only the city he is currently governing?

Only the city he is governor of. This is one of the many changes from MTW.
If he`s outside a city, he does not influence anything but the army he is commanding.

Doesn't his religion have in impact in BI, even when he's not in a city?

[Patricius]

I think that is the only influence on the faction as a whole. Why the faction leader has no faction wide influence apart from that, is mystifying.

Becuase it's annoying and leads to too much micromanaging.

[Viking]

Doesn't his religion have in impact in BI, even when he's not in a city?

Yes, I forgot about that. It counts for X%(minimal 5) conversion in the actual region, plus that he will give 10% unrest in citys that doesn`t share his religion.
