According to legend, Damocles was the revered leader of a vast Nexentrum army. However, during a massive battle, his cowardly commanders abandoned him, and amidst the battle, Damocles was slain.
Enraged at how he was treated despite his bravery, Eira, the deity of revenge, allowed him to come back as a Returned, a ghostly black-armored centurion who would hunt down and kill each of the commanders who had wronged him.
Many Nexentrum commanders carry a dagger with the image of Damocles on the scabbard, which serves as a reminder to look after their men, or they would risk the Black Centurion's wrath, as he would hunt them down to punish their selfishness.
