Now that King Dremin has banished himself, and Dark Kut has been banished by the glove of banishing, you must destroy the rest of the Darkening Sky portals in order to stop them from making a portal to the Realm of the Banished. You no longer have the ability to banish as you ran out after its energy was drained by banishing Kut. You realize Darkening Sky agents are now rouges and have no organized leaders or power. Most have quit Darkening Sky because they know they'll die if they stay. You destroy the 3 portals, and you now feel like their is one more portal to deal with. That is the portal to the Realm of Insanity...
