Final Fantasy III/Sealed Cave

''After gathering with Arc, Refia and Ingus, Luneth would start the quest to restore the Light Crystals, but the earthquake caused a landslide to block the exit of the valley. Moreover, it also unsealed the evil Djinn from the Sealed Cave, and he cast a curse on the people in nearby town. The Warriors of Light need to lift the curse, because they alone could't free the exit of the valley.''

Before the Dungeon
At this part of the game, you start gaining the rest of your party members. This next part is pretty cutscene-heavy, so there won't be a lot of battles.

Town of Ur
After arriving on the world map, walk south until you reach a village. This is Ur, your hometown. If you talk to the first guy you see, an old man in blue, he'll tell you that the elders are looking for you. Go into the building directly behind him, and speak with Elder Topapa. A cutscene occurs.

After this, take a small detour and grab some useful stuff. Go north until you see an old man in orange. Run past him and find a house hidden way back in the forest (You may encounter monsters on the way). Check near the water for a Potion. The old man inside will give you a monologue about hidden switches and examining stuff. Zoom in and interact with any objects that sparkle.

Two of the pots to the left hold Antidotes, and the rightmost candle is actually a switch. Interact with it and a door will open to the right of it.If you take the stairs, you'll see 5 treasure chests. Loot them (Spell Cure, Phoenix Down, Dagger, Eye Drops, and Longsword).

Returning to the center of town, take a path leading northeast to find your next party member, Arc. A cutscene follows. Rename Arc, if you wish, and then watch him run out of town. Check the Water near where Arc was for a Potion.

It's almost time to take leave of Ur, but first, if you wish, take a path leading east from the inn to a well. This well contains three potions.

Now, exit Ur and travel south until you come to the next town...

Town of Kazus
When you enter Kazus, you'll see Arc up ahead. Talk to him (or at least try to) to trigger a cutscene. After that, start exploring Kazus. The town is basically deserted, no one's outside, and everyone inside the buildings seem to have become outlines of people.

On top of that, no one in the shops will sell you anything. To get to the bottom of this, head to the inn and talk to the outline standing by the left-most counter. The outline, who is actually Cid, will give you his airship to help you lift the curse that seems to have caused everyone to become outlines.

Go in Smith's House northeast and check the Vase (Potion). Check the bookshelf in the Inn (Potion). Now go around the wood to find a pond and 3 hidden treasures (Mythril Helm, Staff and Zeus's Wrath).

Head west to a patch of sand west of Kazus to find the Airship. Walk inside and prepare to meet your next party member, Refia (her default name). A cutscene occurs, and your objective is clear: Head to Castle Sasune to retrive the Mythril Ring! To reach the castle, fly northwest (roughly). It appears as a fortress-like structure. Park your airship and go inside.

Note: If you try to go into Kazus with Refia, she will stay outside. She won't go back into town until later in the game.

Castle Sasune
When you arrive, run up to the gate. Talk to the man standing there, and enter yet another cutscene. (Don't worry. It'll be over soon.) After talking to you, he'll decide to let you go talk to the king, and you can now enter the castle.

After entering, go straight forward until you enter the room where the king and the man you saw before are. Walk up to them for another cutscene. Unfortunately, the ring you're looking for seems to have disappeared along with King Sasune's daughter, Sara. You're instructed to go to the cave in the north and look for Sara with the king's man, Ingus, who now joins your party. Now you're done with all the cutscenes, and your last party member has joined you.

You can now head off to the Sealed Cave. However, it might be a good idea to stock up on healing items, and possibly teach your characters some spells or get them armor before you set off. Once you're ready to enter the cave, get on board your airship and head north to the cave across from the lake. Make sure you save!

Let it be noted that Castle Sasune is STUFFED with treasure. There are 3 parts to the castle: the main part, and the west and east towers. In the main castle, some of the side walls appear different from the others. You can walk through these to get into other rooms. Go downstairs twice from the King's Chamber and go through the left wall for a Phoenix Down.

Then go through the right wall and upstairs. Gou around to find 2 chests (Leather Shield and Spell Blizzard), but that is not all. To the left of the 2 chests is another hidden wall you can walk through. Go north, east to find one chest (Bronze Knuckles). Go downstairs twice and get the treasure from 2 chests (2000 gil).

Go to the East Tower where is no enemies. On third etage there are 2 chests (20x Holy Arrows and 20x Wooden Arrows) and on the last etage are 3 chests (Potion, Bow and 20x Wooden Arrows)

Before venturing in the West Tower, go to Ur and buy some stuff for your Party. Train awhile in the West Tower until you're Level 5 or higher, since on the last floor is a boss. On floor 3 there are two chests (20x Holy Arrows and 20x Wooden Arrows) and on the last floor is one chest (Wightslayer), which is guarded by a Griffon monster, so be on your guard.

Sub-BOSS: Griffon
In the original NES version, this enemy was not a boss: in fact, it didn't have the boss music nor the boss animation.

This boss is fairly easy as well. Whack away at it with your swords, and use Potions (or Cure if you have it) if your party members are wounded. Also, it's a good idea to get a Blizzard spell to use not only on this boss but on the boss of the next dungeon. Go to the Sealed Cave next...

The Sealed Cave
When you enter the Sealed Cave, you find yourself in a large chamber. Walk straight ahead, and follow the curving path until you arrive at a two-way split. Keep traveling forward to find a chest (Potion), then return to the split and take the other path to travel deeper into the dungeon. Follow this path until you reach a path that leads off into a small chamber with a chest (Spell Cure). After this, continue to follow the path to a set of stairs.

In the next cave go down-left for a chest (500 gil). Then go to the skull at the top-right corner. Zoom in and you see that it shines. Activate it and the wall will upon up. Continue along the path and enter the next room. A cutscene will play and Princess Sara will join the party. Continue into the next room. With you can speak with Princess Sara if you wish to do.

Go along the path until you get to crossroads and take the path leading down for a chest (Antarctic Wind) and then take the path going up. After you get to the large chamber, go down and get the chest (Eye Drops) then go up slightly and take the path going left. The path will turn down into a large chamber with another path leading to the right. It is advisable to heal your party members as the Djinn is right around the corner.

BOSS: Djinn
''In pre-Islamic Arab culture, the djinns were elemental spirits associated with the air/wind, while the fire-elemental spirits (like this Djinn-Boss) were the efreets/ifrits. The other two elementals were marids for the water and ghouls for the darkness.''

The quickest way to defeat this boss is to use two antarctic winds as they do 350 damage. However, there is alternative which uses one less wind: Cast Blizzard, Use Antarctic Wind, WightSlayer attack, and someone heal. After you defeat the djinn, you will then teleported to Altar Cave, then the credits will roll. Once the credits finish, a Moogle will give a short explanation about the job-change you now can do. Walk past the crystal onto the pink portal.

You could stay Freelancer or change the jobs of your Party however you want (for example form 1 Warrior, 1 Thief, 1 Red Mage and 1 White Mage). For more infos on the five first jobs check Job List.

You will then be transported out of the Altar cave. Once on the world map, it is advisable to save. Go to Castle Sasune where Princess Sara awaits you. Princess Sara will throw the Mythril Ring in the Holy Spring under the Castle to lift the Djinn Curse. After the Curse is lifted, the King will thank you with a Folding Canoe.

NES differences
In the NES version, the first five jobs are unlocked far earlier than here.

The biggest difference is that the man in Ur exchanges your potions with Echo Herbs instead of Phoenix Downs. An Echo Herb just cures the "Mute" status, therefore it's far less useful.

The bow and the arrows can be used by some Wind Crystal jobs, but since the arrows are consumables, you may choose moneywise to save them for the Ranger, that is the job specialized in using this type of weapon.
