Rise of the Blood Sage

The noble family Limerick was massacred leaving only the weak and talentless youngest son of the family head with one of his concubines. He attends the magic academy that teaches their students to become a Mage, but because of his poor talent and weak body he is always being bullied and without a family to support him he was left alone to fend for himself, but he had enough, he suffered enough he is ready to leave this cruel world.
But it seems like the heavens do not agree with his decision.
The old ring that his mother gave him on his eighth birthday, gave him a new lease on life and this time he is determined to take revenge, to get back to those who hurt him, rebuild his ruined family, and stand on top of the pinnacle of magic.
