A little something to make NPC Guilds have some benefits.
This one is to give Thieves Guild members exclusive access to locations others can't go. Can be changed to implement any NPC Guild.
I'm making a thieves guild system somewhat like Skyrim. Where you get quests to do unlawful deeds...plunder cargo etc..
I also thought about giving Mage Guild members exclusive access to Hidden Valley perhaps.
Cutom made Mines set up just for Miner Guild members
Quests for roleplayers on smaller shards.
