My original point, the king of war, was that he was likely taken into Oblivion by the Daedra, as is evidenced by the fact his magic no longer held the Ministry aloft. Since it fell, there are only two reasons: he either willingly allowed it to fall, or was no longer able to maintain its flight due to being trapped in Oblivion.
