Reesong Palace

Reesong Palace is Ganon's stronghold in Zelda: The Wand of Gamelon. It is a large fortress-like castle in the middle of Gamelon. It is considerably run-down and understandably filled with Ganon's hordes of minions. It is here that Ganon has King Harkinian locked up. Once Ganon has been defeated, he'll drop a key that is required to unlock the King. Once the King is freed, the Royal Retainer shows up with the apprehended Duke Onklet who begs for mercy from the King. Lady Alma is also there and when Zelda tells her to stop looking at her stupid mirror and breaks it, she frees Link who was somehow imprisoned in the mirror.

Trivia
