Tosten, like all the sons of the last Hurogmeten, has a lot of issues to deal with. All the Hurogs have some dragon blood in them, but it has been a long, long time since any of them actually was able to change (something that cost Oreg a lot of pain in the early years). I don't know if Tosten will overcome that or not.
I wrote that in, though, to indicate that the Oreg who Ward knows and loves, might not be the Oreg everyone else sees. He's actually a lot scarier that Ward ever notices. And one thing that Tosten can't stand is to be afraid -- he reacts poorly to it.
Fun stuff, thanks. Yes, I'm going to have to get time to play with Hurog again . . .
