Basically the mites that are over you Guardians head is a theorized result of a scientist experiment, the same guy that made SIVA, however It seems that it's running from the thoughts of its user so It doesn't seem to be killing us. Other people found that the word owl was on a tech place somewhere on the web saying it was a orbital weapon lancet, which surprisingly was created by a user by the name of Vanguard posted on 2007.

Other tan that we are still looking at what we can.
