How I udnerstood it , its kind of like a player owned territory in an seperate plane , to show off how well you did in campaigns . Not quite , see the following quotes Kingdoms are smaller versions of the Campaign Worlds , not just social lobbies . You are the monarch of this world ! You can explore , craft , build structures and even fight monsters but a kingdom is limited in terms of both difficulty and power . kingdoms # 2 Eternal Kingdoms are a player owned area where they can create a sprawling town , or mighty palace , fight creatures , create PvP areas , craft items and collect basic resources The owning player is the ruler of their kingdom and can set rules on how the kingdom operates PvP , taxes , etc . They can also allocate areas of their kingdoms so other players can set up their own strongholds and increasing the benefits of players in that kingdom . Edit What I don ' t quite understand is , why is it worthwhile to generate income with your EK ? What is the good of having the biggest commerce hub in the ' plane ' of the EKs ?
