what do you call a gathering of dragons?

Here is my collection of Bisto ware that have decorated with Dragons. This led me to thinking what one might call a group of Dragons: a pride, a party, a swarm, a school, a herd? I have heard the term, "a nest of dragons", but that suggests the place a mother hatches her young, but doesn't really work in this situation. Maybe there is no word for a group of them, perhaps they've always been regarded as solitary creatures. No matter, they look fabulous grouped together here.
