Classes
Demons are widely diverse, almost as diverse as the humans. However unlike humans not every single demon is unique. They can still be classified based on shape, appearance and abilities and both mankind and celestials have devoted centuries on researching and listing different species in hundreds of tomes. Currently most of that knowledge is held in the Council building, some of it still available to humans in churches, libraries and museums. And while humans have since forgotten the importance of the knowledge of hellions who they haven't interacted with for thousands of years, they still remember the two large classes that define the demons.
Hellions
The inhabitants of Hell. Those are all the demons human kind once knew existed and feared. The hellions vary so much in shape and size that it might be impossible to type an individual demon at first glance, even if you know what to look for.
All human mythologies combined might still not be enough to explain the full complexity of Hell and to anyone who tries to face a hellion is likely to perish before they even realize what they're up against.

Surface Demons
There are very few species of demons that are currently found on the Surface. For the most part those are vampires and werewolves. Those are the leftover demons whose existence the Council didn't manage to completely erase after the Great War. The reason was simple - they were fickle. The nature of those two species allowed them to infect the humans with their demonic plague, turning them into something stronger than a human but weaker than a demon. Most consciousnesses crumble under the initial contact, leaving the newborn demon an empty shell consumed by dark urges but some have been known to have preserved their sanity. The Council have tried to systematically hunt down any infected human, often not caring if the infected is still sane or not.
The demons roaming the Surface are, in comparison to the hellions, almost impotent. While still fearsome to humans the surface demons present almost no challenge to the highly specialized Battle and Tamer angels. That's why in recent years some of them have started teaming up and forming cults and sects aiming to summon hellions in search for power. One of the Council's most recent tasks is to sniff those gatherings out and swiftly dispose of all their members, be they infected with a true demonic virus or just with the demonic ideas.

Sub-class "The Protected"
"The Protected" are a special type of demons, not based on their species or shape, but on their social status. Those are either hellions who have established themselves on the Surface or infected humans and families who have proven their sanity and hence gave the Council no reason to dispose of them. They are called "Protected" because the Council ensures they be left alone as long as they don't cause any trouble. That is rather a strategical decision meant to prove the Council as noble and just.
