Dodomai Palace

Dodomai Palace is a large palace and the residence of Duke Onklet. However, since Ganon took over Gamelon, the Palace has been over run with monsters and Duke Onklet has been sealed in his chambers. Hectan now has control of the Palace and has sealed away the Royal Retainer. After Zelda defeats Hectan and frees the Royal Retainer, Nokani Forest becomes available.

Trivia

 * This is one of only two dungeons in the game that has a puzzle of any kind, the other being the Reesong Palace. Zelda must strike the portrait of Duke Onklet in order to get the key required to enter his chambers and complete the dungeon.
 * This is the last area that unlocks another area after its completion, that area being the Nokani Forest.
