Cool Halo clan names?

See, I want a cool clan with a reference in the name that only hardcore fans would recognize. I’ve devoted at least eight years to Halo campaign ( as I am a HUGE fan of the story) but can’t think of any. Now be mature and please help here. I got banned from Bungie.net because of the word “clan” and they must’ve thought I meant the racist scum bags of the K*K

I prefer “Guild”, but lol, I’ve been organizing a guild since Halo 2, and we now call ourselves Cryptum. You could go for Prometheans.
