Welcome to the community, hopefully my county can be of interest to you, while i can't guarantee the location or the tribe (same as everyone else since there is no map yet), I can guarantee the type of cooperation that I will be organising in my county.
First off, my county will be within the kingdom of Nirath, the oldest kingdom in CoE (not just the EU server). Nirath has a wide variety of duchies, and while i haven't committed to one yet, I will come land selection depending on what resources and geological features are available, and that suit the needs of those working with me. That said, it means though I'll have the last say when picking where we settle, everyone will have input in what and where we go.
My counties main focus will be primarily entertainment, at least my settlement in the county will be. The settlements around mine will be areas that support that, meaning short trade routes and locally sourced goods for all stores that sound the entertainment areas. The focual point of the settlement will be an arena, so think peace time pvp :D.
Anything that you'd like to focus your settlement on, i'd support, which means if you want to be a mining town but change your mind to farming later on, i got you covered.
So anything that you want to do, should it involve something to sell later on, be it weapons or armour, food or beer, the central settlement in the county will be purchasing from you as a manufacturer to sell to the masses who come for the entertainment.
If that isn't your thing, then fair play, gg etc :D maybe we'll cross paths later ingame :D
