"For a magic teacher that her highness has chosen, you are very young. Follow me to the testing room so I can determine your rank as a mage."
Old Man William walked out of the receptionist's table and opened a door beside it, prompting Alisceon, Allen, and Iris to follow him as he entered the room.
Entering the door, they saw a crystal ball mounted on top of a pillar situated at the center of the room.
"Place your hand on the crystal ball. It will test your mana capacity, or the amount of mana you have."
William pointed towards the crystal ball as he told Allen to place his hand on it so that it could test one of his capabilities as a mage.
Although mana capacity, also known as either mana reserves or mana pool, wasn't that highly needed since mana control was also important alongside element affinity, it was without a doubt one of the determiners of whether a mage could become powerful or not.
