The Red Harvest is a Dark Eldar Haemonculi Coven.[1a]
The Coven's lair is an underspire of Commorragh that is a bewildering labyrinth. Sometime in M41, Dhaemira Thraex, Archon of the Kabal of the Hollow Heart entered into an alliance with the Coven to take over Port Tavarr.[1a] However Port Tavarr was later invaded by Ork forces led by Ufthak Blackhawk, and during the battle Maculatix was killed by the Warboss.[1b]
