if you could chose to appoint new jarls for all the city and you could any npc in the game who would you chose.

and if you had a choice of becoming a jarls of a city of your choosing what city will it be and why?

Windhelm jarl= Jenassa

Solitude jarl=Idolaf Battle-Born

Whiterun jarl=Knight-Paladin Gelebor

Riften jarl=Fjola

Winterhold jarl=Festus Krex

Dawnstar jarl=Muiri

Markarth jarl=Vorstag

Morthal jarl=Vahlok the Jailor

Falkreach jarl=Ghorbash the iron hand

Markarth like dwemer history and culture and this city is naturally defended from both attacking armies and dragons.

plus if the city gets taken you can retreat into the dwemer ruins and continue the fight or escape.

Oh, well Nazeem would be a great High king, in my opinion.

I'd take most of the Companions and appoint them as Jarls.
