Final Fantasy IV: The After Years/Prologue: Return of the Moon

The Red Wings - Introduction
The introductory scene starts off much like it's predecessor, Final Fantasy IV, aboard an airship of Baron's Red Wings. As Ceodore, Cecil's son, walk around the deck and talk to everyone aboard. After all the talking is done, you'll land on the Adamant Isle. Once you have control of Ceodore again, walk to the small town to the northwest, Mythril.

The Journey Begins - Mythril
Upon entering Mythril, Biggs and Wedge will give you a brief overview of how the phase of the moon can affect your battle capabilities. To view the current lunar phase, just open up the menu with and then press. To advance to a full moon and continue the story, you'll will have to rest a night at the inn. Before you do, talk to the villagers and explore the town a bit. In the tall grass on the east side of town, you'll find a hidden tent (look for a patch of grass you can't walk through and hit to check for hidden items). There's a potion hidden in the tall grass in the northeast corner of town and a Ruby Ring in the grass behind the weapon shop. With the Ruby Ring in hand, talk to the pig in the recess between the armory and weapon shop, he'll give you 500 gil as thanks for returning it to him. Though not much is available, you may wish to buy some weapons, armor or items at this point to prepare for the coming battles. When you're ready to move on, go to the inn and get some sleep.

Recovering the Knight's Emblem - Adamant Grotto
Once you wake up, exit the town and head southeast to the cave-like opening in the mountains. After speaking with Biggs, grab the equipment in the chests before you, then talk to Biggs again and he and Wedge will join your party. Finally, speak to the person guarding the stairs and descend into the grotto.

After heading north, you'll quickly find yourself thrust into your first fight. Biggs and Wedge will likely do most of the work here, you can choose to use only their melee attacks which are more than sufficient to defeat the monsters. As you turn at the top to go down a flight of stairs, Biggs and Wedge will give you an introduction to Band attacks, moves that allow multiple teammates to band together for one attack. To use a band attack, you must first press at the command list then select Band. From here, choose the party members you wish to Band with and then press. With the demonstration out of the way, head south for a potion and follow the path around to the next set of stairs for a tent. Cross the bridge and head northwest for a chest containing ether, then exit via the stairs to the east.

At this point, Biggs and Wedge will send you off on your own. Head through the gold door ahead of you and use the save field to save your game. You can also pitch a tent here to rest and recover. After saving, head out the north exit and follow the path around, being sure to collect the treasure chest items (a bomb fragment and eye drops), to an exit in the southeast corner of the room. In the next room, keep following the rather simple path, stopping to collect items as you go (bronze hourglass, tent, antarctic wind and echo herbs). After grabbing the echo herbs, head south to a recess in the otherwise straight wall. This is the entrance to a secret passage leading to a chest containing iron gloves. Exit the secret room and make use of the save point behind the gold doors, then exit the main room via the southwest staircase.

In the next room, Ceodore recognizes the chest containing the Knight's Emblem, but when you open it...

When the battle's over, Ceodore will learn a new ability (Awaken) and Biggs and Wedge will rejoin the party. From here, just backtrack to the grotto entrance and return to the airship. Once on the airship, tell the soldier you'd like to return to Baron. On the flight back Biggs and Wedge will commend you, only to be cut short by an attack by a pair of Belphegor. They have a lot of HP, but should be rather easy to defeat. Once the monsters are dead, the screen will fade out and you will be in Baron Castle controlling King Cecil.
