Monastarys & Raiding.

Assuming That the lore gets fleshed out and some religions get created monastrys could be a very intresting idea in my opinion...let me explain:

Monastrys:
-Small outposts in remote areas (however in close proximity to powerful factions)
-Crammed full of valuable treasures and rare/unique/expensive blu-prints
-Filled with defenceless monks who can be enslaved or let to live to spread the fearsome news of your raids.
-However they are very very important to particulaur and powerful factions so.the slightest wrong doing against them will piss them off big time giving you noriety and potentially causing wars between you and said faction so the easy plundering can have a major consequence (Imagine several citys teaming up against you to raze your outpost to the ground in retalliation).

Raiding:
-Easy get rich quick method
-Could involve destroying monastrys or potentially occupying them claiming it as your own (mega pissing of factions)

Additionally it could make use of pack animals to act as getaway things to load up and escape with loot before an army arrives.
