Base location near the eye?

So i joined the anti slavers and started raiding slaver locations, never anticipated that the slaves i freed would bolster my squad size from a paltry 11 to 20+. Which means my little watchtower at the outpost near the eye isnt sufficient anymore.

In order not to have to move too far since i enjoy this place on the map (central, not too many roaming enemy squads, close to BDC for good weapons and stealing skeleton limbs for resale) im looking for a base spot in this area, it needs to be fertile since i want to grow my own food, and have a decent amount of all or most natural resources, any suggestions?
