as i see it, the frostmourne room looks like a closed place, with no exit
chains in the sky, no visible walls only blue sky
could it not be part of the final fight...?
arthas attacking the raid, ppl get hit by frostmourne and their souls are sucked into frostmourne, and has to fight the lost souls inthere to keep their free will, while their bodies outside is MC'ed or incapasitated
