What does a "dragonslayer" look like?
I hope he looks like this!
"From the underground kingdom of his ancestors, a sturdy warrior emerges to earn his place in legend. Everything about him - his armor, his weapons, his demeanor - suggests a resolve as unyielding as the stone walls of his dwarven home. With his waraxe at the ready, Tordek stands at the fore of every battle, raining mighty blows upon those who would oppose him."
If that doesn't sound like a heroic dwarven dragonslayer, then I don't know what does! Plus, he's got the dragon motif on his axe and his shield, so I guess it's like a totem animal for him.
