The forces of Chaos spewed forth from the Eye of Terror past Cadia and then disappeared. This is where it earned the name, the Ghost War. The following years saw a game of hide and seek which spread confusion, paranoia, disinformation and deceit. Raids became commonplace in far-flung areas but eventually they went back to the Eye and mankind had to simply wait for the next attack.
During the 7th Black Crusade, the entire Blood Angels Chapter fell upon Mackan to do battle with a vast Black Legion warband led by Abaddon the Despoiler himself. Though they had their full strength behind them and were supported by Rampagers Chapter reinforcement, the aftermath of the battle saw the Blood Angels nearly destroyed at the hands of Abaddon and his primary lieutenants Telemachon Lyras and Iskandar Khayon. Abaddon killed Captain Acrion in single combat, a parody of the duel between Horus and Sanguinius. In the aftermath of the Imperial defeat Carcharodon forces descended upon Abaddon's fleet as they attempted to route the Blood Angels.
After the Black Legion departed from Mackan, the Blood Angels' corpses were found desecrated and their gene-seed ruined beyond recovery. The only exception being the Reclusiarch Thalastian Jorus and his Death Company, who had managed to survive the initial slaughter of their Chapter and launched a surprise attack on Abaddon and his honour guard weeks later. Jorus and the Death Company managed to kill many of the honour guard before being struck down and Abaddon would leave their corpses untouched, sitting upon thrones made from the armour of the Chaos Space Marines they had killed.
