Or is it Bear Dwarf Knights? Or Dwarf Knights on Bears? ha ha
These are from TAG (The Assault Group). They aren't really the right shape for polar bears, so maybe they are a pale version of grizzlies or some species/variety of their own. Great blue bears from the frozen north (in honor of a departed online comrade in minis and gaming).
Also, proof that dwarves can be wizards (bonus figure from the KickStarter for the Bear Knights).
He is actually not the only dwarf wizard I have. I have an much older one, which I think is from the early Citadel days when they did have dwarf wizards.
