The nearest real world equivalent I can find to those enormous talons on the heels of charr feet are the back talons on a bird of prey. However, an eagle's back claw allows it to grip and carry prey. Charr back talons aren't close enough to their toes to provide any kind of grabbing ability, and unless the charr is hunched in a crouch, as when holding a greatsword, those talons never come close to touching the ground. Do they have a use? The only thing I can think of is that they aid a charr's balance when it stands on two legs. If this is so, would a charr be capable of standing upright if the talons were lost or removed?
