"I hooked up with a guild in Valenwood... I think they called themselves the Silver Crescents. Spent quite a few years doing jobs for them. Made a lot of coin, but I didn't care. I didn't really need it... I was running with them because it fit, made me feel alive."
Niruin was a member of the Silver Crescents before he fled Valenwood and joined the Thieves Guild of Skyrim, after his father discovered his membership in the organization and threatened to have him arrested.
