You see an Imperial demon Lord. It holds the rank of General among demons, and very few out rank it in hell.
You see an imperial demon servant. They carry out the whims of the demon lords, and their visage is often used in folktales to keep mischievous children on the right path.
The blue imps look cool but, for a description I’m drawing a blank. Maybe part of the demon servant description would suit them better?
The “their visage is often used in folktales to keep mischievous children on the right path”.
With these kinds of creatures I always lose myself trying to work out details to embellish. What's their chain of command, how do they relate to each other, that kind of thing. That's why I won't go near the dark elves. Anyway let me know if something doesn't work. :)
