Admins are no longer 'High Kings' in the lore, nor are they regular kings. My roleplay character claimed to be king of the dwarves, but those claims were not very legitimate, intentionally. In any case it was decided between Tang and I that he would lead the dwarves into the Exodus, my character went into exile.
I've rebuilt Karul-Thol now, and while it is dwarven in style it is not a place for dwarves to live as such. Thraall is currently the major dwarven settlement, I'm just looking to build my fortress and set up an organisation that deals in storing away peoples valuables in high security vaults. People can still live there, but I'm not looking to run a town nor compete with Tang.
Tang is takin Karuk-Thol's throne room, which was a massive legitimate build as a community effort by dwarves and non-dwarves. If there is anything that should be king of the dwarves, it should be Tang. I don't think there could ever be any 'king of the dwarves' though, just the King of Thraall. One person could never rule all of a single species across altera, just like there is no King of the Humans.
