My current DM is running our base like this. We opened a relationship with breeders in a nearby town, built a stable, and now everyone in the brotherhood is trained in Animal Handling, including new PCs. My psi war has mage hand and training everyone in telekinesis, now all members that have trained at the base know mage hand.Upgradable bases where the upgrades give bonuses to stats/skills or feats. Eg if I upgrade a base with an archery range gain +2 bonus to range attacks kinda thing, or add a Hospital to my Temple and get bonus healing.
Also fun NPC interactions
proficiency + cha at least
