Story
Welcome to Stella Mundo, a magical world still recovering from the devastation of the Mage War that ended the Age of Towers.
Domino, the youngest wizard ever to earn the rank of Archmage, has just begun his study of the ancient Dark Tower, a treasure trove of lost magical knowledge.
But there’s a catch.
As its price for allowing him access to the tower, the corrupt Council of Archmagi has assigned Domino two gifted but troublesome students – Aria, the daughter of a noble family, and Kaya, an orphan with an unusual heritage – and given him just three years to complete their training, a process that normally takes decades.
