Revolution of the 8th Class Mage summary:

Humanity’s first 8th Cla.s.s Mage.
Betrayed, he traveled back 30 years into the past.
The story follows Ian Page, archmage and the first man to break through the 6th cla.s.s, then through the 7th and become the most powerful mage, a 8th cla.s.s mage.
After a lifetime of war and killing, the continent was finally unified thanks to his efforts. Now, old, his wish is to live the rest of his life in peace and try to find salvation for all the blood he spilled. However, his old friend, maddened by paranoia, couldn’t tolerate someone so powerful, so he betrayed Ian and killed him.
In his last breath, he casted a time magic that allowed him to travel back to when he was a young boy. With all the knowledge he previously had, he decided to do things better so he could end with less regrets.
