so I've looked at all these suggestions you've made(thank you) and look over the map and looked at what caught my fancy and will make a list of with pros and cons of each. if you know of any material where any of these places are described please tell me it could help. also feel free to say something if your a late comer to this thread.
1. Dwarf Run

possible access to dwarven crafts
on the map lands appear to be hills and plains close to a river

dealing with dwarfs
close to snakepipe hollow
on a possible lunar invasion router
2. Woods of the dead
Pros
untapped forest lands
close to a road
Cons
full of undead and needs to be cleared
technically owned by the Dinacolli need permission or to defeat them to stay
would need to start from scratch

looks fertile
easy to claim low population

Dragonnewts on one side Lunars on the other
Would need to start from scratch
4. Jomesland

soil is likely highly fertile from all that ash
ruins to inhabit and loot
Holy to Orlanth and Ernalda (the place they wed i belive may be wrong)
