Oh I meant as in 'goons' being a term for henchmen, so wyverns are essentially dragons' henchmen, hence dragon-goons. It's a lot less witty now that I'm explaining it. In fact, you've highlighted to me that it probably wasn't that witty to begin with.

Or maybe that LS thought it was and so I'm just giving an old pun given a new spin.

Because dragon-goon is a bit like dragoon, yeah?
