I always had the feeling, that Juan Atzcapotzalco could have been a member of that family. I would fit nicely with a corrupted Great Dragon and the discussion in the 2.0 Aztlan Sourcebook. That the name Azcapotzalco means 'ant hill' in Nahuatl is interesting in the sense of bug spirits, but with horrors crawling all over the place, they don't fit in.
