The 6 thrones are the 6 demons already trapped within the black soulstone. That big red throne is for the "Prime Evil"(most powerful evil, so maybe diablo?). Belial is the one furthest back in this photo, Baal is in the middle, and Azmodan is the one at the front. Mephisto, Duriel, and Andariel are most likely on the other side. thats my theory, hope it helps :)
