Yes and no. It would be another Divine War, with the Gods racing to stop Mesos from a) stripping them all of their Divine abilities (Corean would be the first to suffer that punishment), b) destroying the Mithril Golem and c) healing Kadum (with the Golem destroyed and Coreans powers stripped from him, it would be almost impossible for them to achieve another victory).
Epic level characters would of course take part in fighting the war upfront, beside the gods, whereas lower level characters would be stuck with either trying to survive or joining one of the many armies (on both sides).
I dont see the lower level characters lasting that long however, unless they get really luck.
