Next to Qin there was Yale Lumen, who was ranked four on the tower. During his studies, Yale was the Crown Prince of the Lumen Empire.
He was also the first person from the Royal family who was able to reach the ninety-ninth floor. Just like Axion, Lumen also shared the element of Light.
After leaving the Academy, he went on to become the King of the Lumen Empire.
Next to Yale, there was another person, known as Jax Lumen, who was ranked sixth in the tower ranking. Similar to Yale, Jax was also from the Lumen Family. However, there were almost three decades of difference between the time of Yale being at the academy if compared with his time.
Jax was a descendant of Yale. However, contrary to Yale, Jax had the element of Lightning. While Yale had a slender body, Jax had a bulky body, despite being around the same age.
