The Night Lords are a chapter of the Chaos Space Marines in Eternal Crusade.
Summary[]
The Night Lords are cynical, ruthless warriors who live to inspire terror within the teeming masses, inflicting meticulously enacted atrocities before each battle to weaken the enemy’s resolve before the killing blow is delivered.
Rather than truly devoting themselves to the Chaos gods, the Night Lords put their faith in the use of fear as a weapon, and make extensive use of jump packs to employ their terror-tactics and hit-and-run techniques.
