Everyone who reached a certain point in their development would one day learn about what was beyond the Terror Grade. This was the Arisen Grade, but getting to it was much more difficult than from Champion Grade to Terror Grade, as training and skills were not enough.
In order to reach the Arisen Grade one had to go through the Awakened Process, and everyone had a different path to this unusual phenomenon.
Some managed to do it during mortal combat, some after years of long training when one day, the fighter finally did not realize his essence, his power.
Some could do it simply because of some thought or philosophy.
For Zayne it was a mixture of the first and the third way, as he fought a lot, and only before the fight with Clort, he defined his path and his concept of justice.
Defeating Clort, when he was able to freely use his power, was the last frontier for him before his mind plunged into darkness.
Crackle.
