The Nine are the nine avatara archmages who led the west during the Great War. Each was a master of the arcane dream magics but even they were matched or outclassed by the Fallen Lords.
At the beginning of the war with Soulblighter, Alric was the only member to have survived. Rabican was killed when The Watcher's army attacked and Tharsis erupted. Maeldun was wounded when he lost Seven Gates to The Deceiver. Murgen and Cu Roi died when they freed The Legion from the Tain by shattering it from within. The other four members were presumed to be dead by the time of Soulblighter's rise to power.
