Legends each have something that makes them unique. These may be ancient artifacts (i.e. Excalibur), witchcraft, or inherent power (i.e. turning into a wolf during the full moon). These powers allow Legends to perform feats that would normally be impossible, but using them always has a cost. Legendary powers have a doom associated with them that will inevitably catch up with the Legend who wields them. Magical swords may have a taste for the blood of the Legend’s true love. Sorcerous Rituals may require blood sacrifices. The cost is always significant and unpleasant. The only way a Legend can use a power without risking the doom is to sacrifice Dross permanently (effectively using up a little bit of the world’s remaining glamour).
