In the Tower of Fangs, Krylancelo Finrandi and Azalie Cait-Sith showed great potential in sorcery. An experiment, however, went wrong and turned Azalie into a dragon, leaving her trapped in that form. The Tower elders cared more about their reputation than Azalie's plight and covered it up. This outraged Krylancelo, who took matters into his own hands and adopted the name Orphen in his quest to restore his sister to her original self. Despite five years of searching, Orphen has yet to find a solution. His quest comes to a standstill until a chance encounter reunites him with his sister. Unfortunately, time is running out as a group of hostile sorcerers pursue Azalie. As Orphen investigates the past to find a cure, he must face the betrayal of his former mentors and comrades. Will he be able to save Azalie from her current state?
