Noxus is lead by swain. Mordekaiser leads the Shadow Isles (basically)
Jarvan IV leads Demacia as far As I'm aware.
Ashe leads the Freljord?
Azir is the emperor of Shurima.
Who leads the other nations?
And if they're not already playable champions, what do you think their kits would be like?
Demacia: Jarvan III is the king and is the leader, because it's a feudal system his power is vested in the power of the royal houses that act as his vassals like the Crownguards: Garen and Luxs family or Fioras' family the Laurents. Jarvan IV is only the prince atm and is next in line to take the throne after his father dies.
Noxus Trifarix: Swain, Darius and The Masked Lady (prolly LeBlanc) hold equal power after Swain deposed Boram Darkwill, prior Emperor of Noxus, he reformed the government so that one person couldn't have too much power.
Freljord: No official "leader", as most of the the Freljord is tundra and wildlands but the biggest tribes are the Avarosans with Ashe as their leader, Sejuani as the leader of the Winters' Claw and Lissandra leading the Frostborn all in conflict to be the dominant tribe.
Shurima: Azir only controls the area around the Sun Disc and the newly arisen capital of Shurima, The northern shore of Shurima is voluntarily assimiliated under the Noxus banner, everyone else in Shurima is either an independant city-state who hasn't allied either way or a nomadic tribe. Xerath is starting an empire of his own in Nerizameth
Ionia, Split into several regional provinces, each with their own governors. The closest thing Ionia has to a leader in Champion terms is Karma as she is their spiritual leader. People who still resist Noxus look to Irelia as a martial leader. Shen and the Kinkou probably hold some sway when they care to intervene in mortal affairs and Zed controls his Shadow Assassins and whatever lands they hold.
Bilgewater: After ousting Gangplank, Miss Fortune holds a tenous grasp on most of the gangs in Bilgewater.
Shadow Isles: Mordekaiser is no longer a Shadow Isles champ in any capacity. His new lore never places him there now he is a Noxus champion. Every spirit that is in the Black Mist is a slave to the mist itself, although there is a pecking order where the stronger spirits like Thresh, Hecarim and Karthus toment the weaker ones.
Ixatl: Qiyanas' parents rule over Ixaocan, which is the cardinal arcology in Ixatl.
Piltover: The merchant clans and the largest families hold most of the influence here. Meaning Ferros (Camilles' family), Medarda and Giopara are probably the biggest ones
Zaun: The chem-barons and their gangs control all of Zaun and have chopped it up neatly between them. Urgot is a leader of his anarchism movement (If such a movement can have a leader.)
Mount Targon: The Solari, Leonas' tribe holds the most power and forces their dominant religion on the rest, the Rakkor are technically the bigger and more powerful tribe, but they have assimilated their traditions and the Solari religion and take orders from Solari priests. The Lunari are a smaller sect who are persecuted by the Solari for worshipping the moon and mostly stay in hiding.
Void: The Watchers
