City state sounds good.
But as I reckon pretty much everyone is going to be a fighter of some sort a mercenary band would work perfectly too. if you think that there will be a core of player in the guild who will essentially be the leader as this chosen men, then depending on the guilds success more people will join in. and if we're going to be mainly pvp orientated then it just makes a lot of sense. Plus hyboria is full of mercenaries as far as i understood from what i've read.
Then, if we get enough people and a high enough guild level we can build our own city to show how powerful and awesome we are.
But yeah, either of those ideas if good for me.
