Opening the sealed doors
This is actually a rather short dungeon.
Go through the entrance, then head north and enter the main hall.
Then walk straight north to the next screen. Walk further north, and take the stairs in the east, and walk all the way south and activate the switch to open the door.
Walk back north and take the stairs on the east you just passed before. Grab the treasure just there.
Walk south, and take the stairs here again to reach the treasure in the northeast corner.
There is another treasure in the south behind the door you opened before on the southern screen. After collecting it go back to the center of the northern screen.
Now go to the west side and walk south till you reach another switch that opens the door nearby.
Way to Ishtry
Backtrack to the entrance of the dungeon, take the stairs in the west, and follow the now open path to the next screen.
Grab the treasure on the eastern path here, then take the stairs you passed before and grab another treasure in the north. Go east and north from there to leave this area.
Activate the Porter, heal your team and prepare for a boss fight.
After the battle the surroundings change and Ishtry vanishes deeper into the dungeon. Use the Porter to heal your team in a town then enter the last dungeon in the north.
You don't have to finish up all side quests at this point - there's still time to do so before the final boss battle (I'll mention it in the walkthrough later).
