Angels as a race.

By the way, there is one more snag... In the world of "Heroes 5", angels are servants of Elrath, and he already has one race—there will be no second! So these angels will have to be called something else; and at the same time, a patron dragon must be thought up for them. In my opinion, either Asha herself would suit best (since this race is opposite to the demons who worship Urgash) or that third dragon whom Urgash killed...

Explain the phrase "So these angels will have to be called something else". Does this mean coming up with different names instead of the Michael, Gabriel, etc., that I suggested? Should the patron dragon be chosen from existing ones, or should I invent something of my own? And in general, is it really so critical to have a patron dragon for a race characterized by the struggle against these very dragons, whose form Satan often assumed.
