18+ Dragon-Devouring Mage

[You will be the cornerstone of a new mythology. For the sake of that mythology, I will grant you another chance.] The last successor of a fallen founding contributor family and cursed third-rate mage, Russel Raymond. He hoped to revive his family’s societal status but was expelled from the academy. All he could do was work as a mercenary third-rate mage. One day, on his way to his temporary job, his mother’s memento ring, the “Dragon’s Heart,” reacts, and Russel is given an unexpected chance. He “regresses” back to his days in the academy. [You have received a mana stone (consumable) as a mission reward.] That is how Russel begins soaring in life. Like a dragon who never got to spread his wings. He crosses the waves called fate that had pressed down on him and fly into the bright world he was previously banned from.
