I wonder if Lloyd can double the speed of the backpack. If so, Cubbins uses hat magic to access whatever assets he can scrounge from anywhere in the Kingdom to get the funds to make Tramennis an heir. They take out Ossomer with Ace, Cubbins, and whatever ground troops remain. Slately engages the archons with unipegatuars and orlies, a suicide mission, but one to keep a stack occupied. Pierce revives Tramennis after they put the pack on him. Lloyd doubles its speed, and before Tramennis even comes to consciousness, they fire the pack, shooting Tramennis farther than any GK dragon could possibly travel in a turn. Lloyd and Pierce then join in the fray, doing what they can before being croaked. Once Slately sees Tramennis has escaped, he disbands the entire city ala Queen Bea, leaving Wanda and the Decrypted, Jack Snipe and Vurp (the only non-decrypted left) on the field, maybe Hamster and Sizemore (depending on what happens in GK), and, of course, Bat*3!
They are now stranded far from GK, no teleportation circle to get them home. The rest of the story is an Odyssey-style story of Wanda, Hamster, Jack, Sizemore, and a steadily declining roster of decrypted as they travel through all the kingdoms between Jetstone and Gobwin Knob -- Haggar, Carpool, Sofa King, and others -- before Jetstone and Transylvito recover sufficiently to re-recruit FAQ and mount their counteroffensive. Along the way they have to deal with an idiot Stanley (unable to help directly because Maggie is incapacitated by backlash from Stanley snapping out of the suggestion), a Machiavellian Charlie, and various factions of the Magic Kingdom.)
