We'll have to remove the word "angels" from the race name altogether.
Sorry, the world of Heroes and our world are different things. If angels are going to fight dragons here, it will be, to put it mildly, nonsense. In Heroes, Satan is a dragon, and God is a dragon.

If we remove the word "angels" from the race name, the whole meaning will be lost. That's one. Two, I didn't say that angels should fight dragons; I just wanted to say that they could very well have a different type of creature as their deity. Regarding the dragon-deity. In principle, Elrath could be used as such. It all makes sense: initially, he sends only part of his army to help humanity (tasking them to eternally serve pious people) - angels and archangels (they will remain in the Heaven race even after the introduction of the angel race) - but seeing that things are not going well for humans, Elrath sends his entire army to fight the enemies.
