The Night Sentinels are a warrior caste of Argent D'Nur who were originally formed to serve the King of the Argenta and protect the Wraiths. They were scattered after Hell conquered Argent D'Nur, but they were never entirely destroyed. The soul of a Night Sentinel appears to the Doom Slayer in Argent D'Nur.
