I've considered that the forsaken might be outside of one of the factions - but a lot of them visibly settled into cities and positions of power in the book. For instance, the leader of Illian was a forsaken who had created the identity of some minor lord and then risen to power in the government. So I wouldn't be surprised if the forsaken is in one of the factions masquerading as a good person.
