Not to be confused with the severed heads, one of Azeroth's finest heavy metal bands, The Severed Threads are a group of nerubians that have had enough of Queen Ansurek and are looking to remove her from the throne. A fine example to be setting depending on your locale's current political climate. I guess she did some bad stuff or is a bad leader or something? I'm not sure, I'm not a nerubian. Not my queen. But mostly you'll be interacting with three of the nerubians that are looking to overthrow her in their power hungry bid to rule the nerubians. That, or make a better life for them. You pick.
