Citadel Walk-Thru
The Citadel is on the isle of Isamu-Jima in Tokuno.
From the Mt. Sho Teleporter, run straight East until you encounter a small fishing village.
Inside the small cabin you will find a moongate to enter the dungeon.
Reach the border and teleport into the main garden.
Now you have to move from one room to the other one, activating four secret doors, to actually enter the main room of the building. Enter the east room and step on the gray tile.
This will open the door to the south room, near the wall. Enter that room and move to the tile near the bed.
The tile will open the door to the room on the opposite side of the garden. Run north, enter the room and double click the... thing.
That will open the door to the room on the south-west corner of the garden. Run there and move one step away from the south-east corner of the bed to open a moongate.
The gate will take you in the main room. Kill the Black Order Grand Mage for the Dragon Flame Key. To enter the next level jump somewhere in the middle of the carpet near the southern wall of the room.
The carpet will move you to the next zone.
Go upstairs
and step on the wooden chair.
The chair will take you in the "book" room.
Here you have to collect 7 books and drop them into a barrel to open the next door. You can buy the books from a provisioner if you don't want to wait too long for the books to spawn in the room.
After the gate walk until you reach the south corner of the room and move upstairs.
In the next floor you have to step on the tile where the stair is to open the door to the statue. Double click the statue
to open a gate near the stairs.
The next room is the most convoluted. First you step on the bench, then you have to crash into the painting to activate it.
Next, move to the other side of the room and step on a darker tile near the secret door, then a bit back on two more tiles.
That dance will open the door to the room where the statue is. Double click the statue to open a moongate.
Jump in the moongate and you'll reach the next room. Here you simply have to double click the wall to open a secret door.
DON'T FOLLOW THE STAIRS ON THE RIGHT! Move west, kill the Black Order Master for the Tiger Claw Key and continue west down the stairs.
Downstairs you'll find the Black Order High Executioner to kill for the Serpent Fang Key. Step on the bench to open the door. Also found in this room is the Citadel Elixir Chest. To exit, double click the lever near the door.
Head downstairs again. Double click the northwest brazier to open the door in the south wall.
To reach the stairs to the upper level you have to pass a hidden path. Or you can simply teleport.
And here we are, the final dance. You have to move on five tiles to trigger the last door. The last step is right in the north-east corner of the room.
Walk north and you will find the altar where you drop the three keys collected from the masters of the citadel.
