Orida Fortress
To reinforce the Yabba race getting attacked up north, the entire defensive line went into action. Soldiers were brought over, and supplies were transported. As the core of the defensive line, the Orida Fortress was obviously the busiest. Everyone was up to their necks in work.
Of course, those matters had nothing to do with Link. He only had one task—to train Magicians and complete the Soul Slalom Magic Seal to combat the Dark Serpent.
The Orida Fortress contained three Mage Towers. The two subordinate towers were similar to the Mage Tower of the East Cove Higher Magic Academy. The main tower was practically equal to the Heaven's Thorn Mage Tower.
There was a 300-square-foot garden between the three Mage Towers surrounded by a low wall. This was the Magicians' independent area.
Link practiced the magic seal with the Magicians here.
