The Knight plays a small role in Nomad's Requiem. After talking to him, he will die and the player must examine his body to figure out how to survive the room next to him. The player gets a clue about being "only the pious", which means the Piety prayer will be helpful in the next room.
Trivia
- Whilst conversing with him, the knight reveals he is an agent of "The Master" who Nomad has betrayed and was the one that set up the explosives in the room.
