There is no place as safe and protected as a castle. And not just safe but symbolic too: They represent the innermost chamber of the soul. These qualities give us a clue about what the game’s creators hoped the players might feel when battling from tower to tower.
Castles are traditionally the safest place in a kingdom, and indeed, Org wanted the treasures of the towers, the fruit of the tree, and
the resting place of his bride Yun to be very safe. This is why he has employed us Guardians! And because the castle is floating in the Celestial Sky, it cannot be easily reached.
Also, keep in mind that each tower represents a different memory. Each represents an episode or event from Org’s life with his beloved Yun. By making your way through each field, symbolically you are making your way through the life of these lovers. Hopefully this path of trials through the towers will help you appreciate what it is that you are protecting and fighting for.
