Nredz are apparently a faction in the My Immortal verse, though they seemingly do not wield much political power. They are mentioned in the Author's Note for Chapter 25, where Tara threatens her flamers that the nredz will put "vrtuz" in "ur computer". Truly, they must be virtuous indeed. Nerds may be allies of Tara due to the historical out-casting of nerds in regular society, but this ally-ship may be only one of necessity. Since Nerds are stereotyped as having brains, they may be a part of Ravenclaw, though they might be with the other geeks and normies in Hufflepuff.
