There is a staircase north of where you met FuSoYa. You can find 280 Gil by pressing A on the stairs, and if you go up it, you'll find eight more crystals, revealing that the Moon has its own Light and Dark Crystals. By interacting with them, you'll learn that they keep Zemus sealed in the moon's core. You can get on the teleportation title to enter the core, but you won't get very far as a barrier will stop you.

Before you go back to the Blue Planet, there is an octagon-shaped area on the lunar surface. Land on the north end of it with the Magical Ship, then enter the cave in the center. This is the Cave of the Phantom God.

The Genji Gauntlet (aka Genji Glove) can be equipped by Edge, and gives him a lot of much-needed physical defense. Give the Rune Ring to FuSoYa to increase his Wisdom and Will.

The DarkWizard is weak to Piggy, and the Moon Goddess is weak to Mini. You'll want to cast Piggy on the former to stop their spells. The latter are easy to kill, and you can also steal Artemis Arrows from them. Steal at least 80 of those with Edge's Sneak command; you'll need those for Rosa a little later on to deal quadruple damage to the dragon-type enemies near the end of the game.

There is a secret passage just to the east of the start that leads to a Genji Shield, though it won't be better than the Aegis Shield for Cecil.

The Silver Dragon are weak to Mini, and you can also kill them with Quake.

The Genji Armor is one of the best armors in the game for Edge, and it works wonders for his defense.

The Demon Soldiers here don't continuously cast Stone Gaze. They are weak to the Tornado spell, and are impervious to just about any status ailment you can throw at them. They also attack with laser beams and flamethrowers and have a lot of HP.

The Genji Helmet is another useful piece of armor for Edge that will work wonders for his defense.
