Lunpa Fortress

Lunpa Fortress is an optional dungeon accessible from within Lunpa in Golden Sun. It is where Dodonpa and his empire of thieves and bandits stake their claim and rule over the town with an iron fist, while his father Donpa has no say in the matter. Late in the game, when Isaac's party has attained the Cloak Ball in Tolbi at Gondowan, this dungeon is available and can be entered.

Using Cloak to stay out of the sight of patrolling guards in stealth gameplay is the emphasis of the dungeon. At the end, in the cavernous bottom, the party fights an optional boss named Toadonpa. Afterwards, the town's weapon and armor shops will open up and their powerful artifacts will be available.

Walkthrough
Inside the fortress, head through the first door immediately. Note that the area is very similarly lit to Altmiller cave; there are torches on the wall that spread out in circles. If you enter the area lit by a torch, you will be revealed. In the door directly ahead of you are several henchmen, as well as a few servants. Talk to them if you wish; in the main hall, go down the right path and head north. Use Cloak to hide from the green men, who will throw you out if they see you. Go through the door, staying out of the light as long as possible. The next room, head north around a wall to stay out of the guard's sight, going into Cloak whenever possible. Once past him, go through the door.

This room has a walking guard. Wait for him, in Cloak, to go as far left as he does, then quickly dash by heading south and through the door. In here, use Cloak immediately, then run south and up the stairs. There is a guard pacing very quickly back and forth, but he doesn't come any closer. Walk right, then go through the door. Once entering, you will see a red guard this time, instead of the usual green. As soon as you are in the room, you're already in the light; Cloak is impossible to use. Walk by, and he fights you. He's very weak, so don't worry about it. After he is defeated, you can go north up the path he was formerly blocking. In here are Dodonpa's wife and kids. Talk to them if you want to, then return to the room where the guard was.

Go back one more room to the area where the two guards were pacing quickly; use Cloak and try to run past him, then head right into a small area where his light doesn't reach. Wait for the second guard to go as far left and run past again, just as before. Once beyond them both, head north through the door. In this hallway, the door directly in front of you leads to a room where two women are being held. There are no guards here, so just run and head through the next door. As soon as you do, you are challenged by three men. Take them out, just as before, and then walk into the next door. Head south, and don't bother with cloak. You'll be faced by yet another Brigand. Defeat him, and go into the door he was blocking. Inside is Donpa, sleeping, and a servant watching him. Talk to her to initiate a short cutscene, then go back out.

In the next room is a guard who walks in a "U" shaped pattern. Wait for him, in Cloak, to come up the left side, and as he is turning around, dash down the left path after him, without going into his light. Pass through the door, and walk up the locked jail cell door. Use Catch to grab a Cell Key that is sitting on a barrel. When in possession of it, every locked Cell door in the fortress will open as you approach it. You can unlock the door in front of you and battle the Brigand on the other side now. When you defeat him, go down the stairs, then in that room down another set of stairs, ignoring the cell door (it just leads out.) Walk left over to the pile of leaves, and use Whirlwind to blow it away. Once they're gone, Reveal will show a button that was hidden behind it; hit the button to open the door. This leads to a cave-like area with water flowing through. Monsters will start appearing. Head north up the right path until you see another pile of leaves, then use Whirlwind and walk through the exposed door. Head north until you see three locked Cell doors. The center one has a treasure chest containing Power Bread, while the other two are empty. From here head south and through the door. Open the Cell door in here, and use Move to slide the large box all the way south, until it falls off the edge. Stand on it and jump left. Keep going down this path, unlocking the cell door, until you come upon another pile of leaves. Whirlwind them away, then Reveal to expose the button. Push it, pass through the door, and save. Opening the Cell Door in this room, you finally see Hammet. A cutscene begins between Hammet and Ivan; the reunion isn't long before Dodonpa bursts in. Dodonpa trips a lever and sics his beast on you.

Enemies
Note: The Brigands are only fought in the upper portion of the fortress, while all the other monsters are found only in the basement.
