I think one of the primarchs was never found, as per http://warhammer40k.wikia.com/wiki/Thread:43631, but maybe the legion fell to chaos without a primarch. Also, it would be cool if the primarch was to just come back out of the darkness and just lay waste to the necrons, chaosers, and similar peoples.
