Head back to Kukuro's house in the southeast corner of the underworld. You'll be able to get the Holy Sword Excalibur now that you have the Magical Ship. Equip it on Cecil; he will need the attack power.

Be ready to equip Ruby Rings, as you're going back to the Sylph Cave in the northwest corner of the underworld.

Head back to the Sylphs' house and use the Frying Pan on Yang to wake him up. Yang will finally come to, and tell you that the Sylphs saved him from death. The Sylphs also offer their aid by becoming a summon for Rydia, and when called upon, they absorb a small amount of enemy health and give it to the party.

Head back to Fabul.

Talk to Yang's wife again. Hand her the Frying Pan, and you'll get the Meat Cleaver in return. Believe it or not, it is one of the best weapons in the game. You can only use it as an item in battle, and it deals 9,999 HP worth of damage to anyone you throw it at.

Head back to Baron Castle, since you've met the Phantom World.

Head back to the hidden throne where you found the ghost of King Baron. Now that you've been to the Phantom World, King Baron will show up again, and reveal that he became the soul of a Phantom Beast upon death. He offers aid as a summon for Rydia, but you must beat him first.

You'll then face Odin. Have Edge cast Raijin, have Rosa use the Blue Fang, and have Rydia cast Bolt 3. The faster you kill Odin, the less likely that your party will be wiped out. When you win, you'll be able to summon Odin in battle with Rydia.

Head back to Mysidia and get on the Magical Ship.

Magical Ship

Map (by FlyingArmor)

There are rejuvenating chambers that act as a free inn to the south as well as a Fat Chocobo.

The helm at the north end of the ship lets you fly around like you would with the two airships from earlier in the game, while the red crystal is the Crystal of Flight that will take you to the moon when interacted with.

The Moon

There isn't much to the lunar world. South of the castle is the Cave of Hummingway, which is surrounded by mountain. Park the Magic Ship there and go inside.

Hummingway's Cave/Cave of Hummingway

There are a ton of Hummingways that look like Namingway, and one of them sells things when you talk to them. The Flute allows you to summon the Fat Chocobo anywhere in the world, but at this point, you have one on the magical ship.

One of them is actually a Namingway, strangely enough.

The Hummingways at the north have speial palletes, and the one on the left mentions the Namingway that went to the earth.

From here, get on the mountain area and land north of the castle that you see. You'll be heading there next.
