Hesed of the Black Anvil Guild:
It's a horrible virus that takes away control over machines. Golems infected with this have allied themselves with the Spiculas! Oh, did I mention that Spiculas and Kamaels look very much alike? Almost identical, except... the location of their wings, maybe. They also use the same weapons as Kamaels too. Though, to be fair, the Kamaels can now use all kinds of weapons since Awakening, but yeah...
"So why did these Spiculas start appearing in the first place?"
