Every city in Thracia has a single hero. The hero is the leader of the army either in battle or while exploring the map. This is the only unit of the game that can evolve in time based on accumulated experience and honor. The two can only be earned as a result of victory in combat or completion of quests. When a certain amount of experience is reached, the hero is promoted to the next level. With each level, he gets to learn more powerful abilities and spells that he can later use during battle.
