Rock lichen?! That doesn't sound very edible...do dwarves have different stomachs than humans? Or are you usually very, very hungry in the mornings?
Of course they can, but Salma won't, if she isn't scared or angry or trying to defend me. Or if I tell her to, of course. But it's a possibility I guess - I once saw a man flying over the whole training yard at Highever, when one of the war horses had kicked him.
