As soon as you walk out, you'll see the Red Wing fly by to destroy the castle.

1. Go straight north to 3F. A cutscene will occur, Tellah will leave, and a new member, prince Edward, will join the party.
2. You'll obtain a Hovercraft, which allows you to cross shallow water with rocks.
3. Get back inside to collect treasures in the far north room. Inside, talk to the injured guard; he'll disappear. The switch is on the wall above the guard.
