I'm a short story person, and I tend towards science fiction and modern fantasy. But it seems that, at con workshops, I always get novels. And these novels are almost always classic fantasy ("high fantasy") with kings and queens and princesses and medieval settings and dragons and quests.
It's not a part of the genre I normally read, and they're novels, so I don't know if I can be any help. I end up concentrating on craft issues (text, dialogue, description) and talking about my opinions of how a novel and a fantasy story should start. There's a decent chance I'm way off base on this stuff.
I'd just like to get a couple short stories in a more familiar genre. Maybe next time. I'll be interested to see how the session goes overall.
