— Deimos

Deimos is the fourth and final boss in the Bastion of the Penitent. He is a powerful demon feasting on the suffering and despair of a specific prisoner.


Deimos, like all demons, was born in the Mists. At some point in time he struck an accord with the mursaat, becoming an agent of the Unseen Ones. He tormented their valuable prisoner, Saul D'Alessio, who was locked deep within the Bastion of the Penitent, in order to break his psyche and turn him into the mursaat's puppet while feasting on his suffering. Due to the bastion being built in a location where the borders between the physical realm of the living and the Mists were less strict[1], Deimos could oversee Saul from the comfort of a demonic realm and pass over to the physical realm whenever needed.

When a raiding party reached the heart of the bastion in 1330 AE and some of them were drawn into the demonic realm while trying to free Saul, Deimos attempted to stop them but failed. He manifested in the physical realm to continue the battle and intimidate his opponents. The demon continuously taunted Saul and the raiders and even ended up drawing the party into the demonic realm in order to finish them off there.

However, Deimos was defeated for good when, against his expectations, Saul overcame his personal demons and joined the raiders' side. Following the demon's demise, the party returned to the physical realm. The victory was bittersweet, however, as Saul passed away soon after, finally freed from centuries of torment.

  • Deimos has 2748 armor (1374 toughness and 1374 defense).

  • Deimos has 36 million hit points.


  • Deimos is the god of terror in Greek mythology.

  • Developers of the raid wing officially left it ambiguous if Deimos was a manifestation of Saul's guilt in his mindscape or a physical Mist entity initially unrelated to him and later assigned as his tormentor.[2] However, Creature Artist Chris Bennett who designed Deimos calls it "Saul's Demon" and states "This creature is the manifestation of the all the inner demons of the character, Saul D'Alessio."[3]
