Traitor Heroes are from the set Servants of the Betrayer, and they are just like normal heroes except that:
Instead of a Specialisation (for example Frost on a Mage) they have Traitor.
Traitor is just like a Specialisation: it enables the hero to play Traitor Hero Required cards.
All heroes other than Traitors are considered Loyal.
