We've all heard of a flock of doves, a murder of crows, a gaggle of geese, but do you call a gathering of dragons? Would the grouping be similar to birds, or to reptiles?

I did find one source for animal groupings, but of course it doesn't mention dragons since they are mythical beings. Still, ideas: http://www.thealmightyguru.com/Pointless/AnimalGroups.html

So this begs the question, what do you call a bunch of dragons?

A thunder

An Ohshitgettothebunker of dragons

Dragons travel in flights.
