Much like his half-brother Cthulhu, Hastur can create small clones of himself to act as his minions. Unfortunately for him a handful of them have broken from his control and rebelled against him. Now living under a species-wide witness protection program within the local galactic community, these former minions often work as consultants in matters regarding "chaotic fluctuations in space/time", a.k.a. magic. Many carry an Elder Sign in order to ward of any possible attempts at Hastur regaining control over them.
They're also one of the few races to know that Idiot Fluteplayers are more than just a noisy nuisance but the key to one of the greatest secrets of the universe.
