Devastators are fiery and horned demons, renamed (the name wasn't very good - the race is demons, and the unit name "demon" is the same as calling a swordsman "a man with a sword").
Devastators are the ones from which cyclops originated - demon-architects of Shio - I don't know what is specifically meant by "architect," but from what I've read, it's clear that there were such one-eyed demons with the "Eye of Urgash," which was inherited by cyclops.

And isn't it a bit too much to make 3(!) of the last levels flying units? Maybe it would be better to use Nightmares? And you've somehow weakened Phoenixes too much...
