[Knives is given two species he's unfamiliar with, but he just nods. He'll visit the library later on to get a better idea of what the rest of the universe thinks a dragon is, and what a nymph is beyond Greek myth.]

I had no idea vastly different species could interbreed. The only dragons of the world I know are.. great worms of a sort. Very intelligent, desert-dwelling hive creatures.

[And now mostly dead for trying to stick a mind control bug in his ear. Knives wasn't terribly forgiving.]

It will be interesting to discover more about other species as time goes on. Do you enjoy hybrid vigor, compared to your parent species?

[This last is a touch cautiously; if dragons and nymphs didn't get along well she might well be an outcast, and might not be interested in discussing it much. Knives wouldn't ordinarily bother with any concern but well.. there's no human in her at all.]
