From Naakhtkha's Palace, head southwest to Haaggkhen's Castle.
Use the Unlock spell to get the drawbridge down and touch the symbol farthest to the right to deactivate the energy field.
Go north, then go west. Unlock doors as you proceed as necessary.
Enter the door with the "Sn" over it and then quickly exit north again because the checkerboard room constantly drains your HP.
Go west in the room with the pretty outdoor view, and then go south.
Kill the enemy and go west. When you think you're prepared for the boss, go north.
Talk to Prince Haaggkhen to start the battle with him. For whatever reason, he is not as difficult to beat as Princess Naakhtkha was. As long as your party is fairly strong, and has some good weapons and shields, he should go down after only a few hits with minimal damage to your own characters. Strong swords work best, like Sabers and Dragon Swords, but if you're having trouble, have your Magician use Anti-Matter and your Priest/Priestess use Fireball. When you're done, you'll have the Seventh Tear. Only one left to go.
