Dunno about that but inc new kingdom troop images. (Editing as I go)
King Mikhail (Boss)
Asbjörn Doomclaw - Possible Mythic
Baba Yaga (Quest Troop)
Also Silverglade mythic artwork probably?
Also interesting text related thing from the kingdom quests:
Quest 3: "Killing Abhorath (again)"
More from the text files.... new kingdom (after Urskaya) hints... maybe our merfolk one finally?
The seaweed is always greener in somebody else's lake.
