The Wyvern at Castle Deist can't speak to humans. A Pendant hidden in Deist Cavern solves that. This chapter covers two trips to the cavern and the story that unfolds between them, ending with a surprise back in Altair.
Deist Cavern - The Pendant
Exit Castle Deist and walk directly north. Deist Cavern is right there in the mountains.

Inside, there's a chest immediately to your right (230 Gil). Head to the top right stairs on B1. They take you one floor down. Grab the Pendant and leave. That's all you need for now.
Return to Castle Deist
Go back to the castle and enter the room next to the mother and child. There's a dragon inside. Show it the Pendant.

With the Pendant, you can understand the Wyvern's words. Ask about the Wyverns keyword. The dragon reveals what happened: the Empire poisoned the water, killing nearly all the Wyverns. This one is dying too. But it has an egg.
The dragon gives you a Wyvern Egg and asks you to take it to the Life Spring deep inside Deist Cavern. That's the only place it can hatch. Shortly after, the last Wyvern dies.

Deist Cavern - Full Exploration
Head straight back to Deist Cavern. This time you're exploring all 5 floors, grabbing 12 more chests, and reaching the Life Spring at the bottom. Three routes branch from B1, so expect some backtracking.

B1. You already grabbed the 230 Gil chest on your first visit. Take the bottom left stairs to start Route 2.
Route 2 - Bottom Left (Chests 2-6)

Go right and grab Chest 2 (Ether). Take the stairs to the right of it. This kicks off a linear path that runs through B3 and B4, eventually dropping you at a dead end on B5.

Four chests sit at the B5 dead end in the bottom right of the map: Chest 3 (Knight's Armor, monster chest with Adamantoises), Chest 4 (Saint's Spirit), Chest 5 (Sage's Wisdom), and Chest 6 (Flame Bow). Use the Saint's Spirit and Sage's Wisdom on your spellcaster. Teleport out and re-enter the dungeon. You're taking the bottom right stairs next.
Route 3 - Bottom Right (Chests 7-13)

Follow the path until you reach the top of B2. Take the first path going down to grab Chest 7 (Mythril Helm). Then follow the north path for Chest 8 (Mythril Armor). Go south from there and down the stairs to B3.

Don't cross the bridge or you'll fall. Grab Chest 9 (Mythril Gloves) and Chest 10 (Mythril Mirror) from this island. Follow the path around for the second chest, then head back up the way you came to B2.
On B2, go straight up and take the first left. Follow the path down to Chest 11 (Mage's Staff, monster chest with Green Souls). Continue north and follow the bend down the stairs to B3. Chest 12 (Mythril Shield) is right there when you arrive.

Go north. Do not cross the bridge. Instead follow the path north; it takes you around to some steps down to B4.

Chest 13 (Acid Phial) is on the left side of the room. That's all 13 chests. Take the stairs down. Follow the path until you see four doors. Take the third one.
At the deepest floor, four Chimeras block the path to the Life Spring.

After the fight, approach the Life Spring and use the Wyvern Egg from your inventory. The egg sinks into the water. It won't hatch anytime soon, so Teleport out.

Altair - The Lamia Queen
Return to Altair. Leila leaves your party to head back to her ship.
Make for the upstairs room and speak with Hilda. Something's off. She acts strange, and invites Firion to her room. It's a trap. The "Hilda" you rescued from the Dreadnought was actually the Lamia Queen in disguise. She reveals her true form and attacks.


After the fight, Gordon shows up with the real Princess Hilda. The impostor has been exposed. Gordon rejoins your party. Speak with Hilda to learn about your next mission: the Empire is holding gladiatorial games at the Coliseum, forcing captured rebels to fight. Some of your allies might be trapped there. Time to infiltrate.
