If I recall correctly, there should be NPCs at the Moonglow Illusionists Guild, but the building is empty.
Populating the world with NPCs other than the expected vendors is going to be a very long work in progress. Not to mention NPCs are largely non-interactive by default (they don't have much in the way of conversation).
I can take a quick look at putting some NPCs there. Feel welcome to let me know about any empty buildings, our NPC package is mostly just what comes by default.
Cool, no big deal. I just remember that there used to be NPCs there who sold reagents. IIRC there were four, with two of them being mages, one an alchemist, and one a guildmaster. The reason I recall this so well is because I used to murderize them regularly for their colored sandals.
I've checked this on a demo server and there were indeed NPCs in this building. Mage and alchemist vendors.
1 Mage vendor
2 red robed alchemists
2 herbalists
Thanks, I have
added these in.
