Many Magicians had left the academy to join the army, though Link took no notice of this as he was busy in a mid-level Elemental Pool. He was skillfully manipulating the magic seal and was engrossed in his spell experiments.
Just as its name would suggest, the Elemental Pool's appearance resembled that of a pool. There were five of them, each housing the five basic elements: metal, wood, water, fire and earth.
Each of the elements was of a distinct color and the colorful pools were placed around the perimeter of the expansive room along with the controlling magic seal. Once the magic seal was triggered by the presence of active Mana, a Level-5 Guarding Barrier would then be instantly activated.
A layer of thin translucent barrier enveloped Link's body. It might seem fragile, but it was indeed powerful enough to protect him from any magic spells that were below Level-5. This meant that even Flame Blast wouldn't be able to do anything to him now.
