Gley Story in The First Descendant

“If you keep looking after others until the very end, who looks after you, mom?”

Dia Elias asked her mother. ‘Until the very end’ was the slogan of Albion’s Medical Corps, and it was the first time that their captain, Gley, faced someone who questioned this slogan. A question that had never been asked by, nor asked to, someone who had declared and lived by this slogan all her life. Hearing this question from her own daughter brought about complicated emotions within Gley, but she could not grant her daughter’s request to allow her to protect herself. Gley, who had lost her entire family on the battlefield, was afraid. If she were to lose her daughter as well, then she would lose everything.

Undeterred by Gley’s stubbornness, Dia went to her mother’s old colleague and fellow military academy professor, Ajax, for a recommendation letter and thus enlisted in the military. Gley, feeling betrayed by Ajax, who knew of her past scars and yet still wrote the recommendation letter, refused to even speak to him.

Despite feeling much concern over her daughter who had stubbornly become a soldier in the end, Gley decided to give Dia a chance and trust in her decision which she would end up regretting when an incident occurred, in which all forces that had been deployed to the Vespers strike operation, excluding the Descendants squad, suffered massive casualties, with many going MIA. Among those who had gone missing were Gley and her daughter. While Albion Headquarters frantically searched for the missing personnel, Gley and Dia were subjected to horrible experiments performed by the Order of Truth. The mother and daughter duo were used as test subjects for the Order’s experiments to create a new ‘species’ by injecting Vulgus DNA into human bodies. Gley despaired at her situation, as she could only tremble in anger helplessly as her daughter’s agonizing screams echoed around her.

Gley is a highly versatile character in The First Descendant, offering a unique high-risk, high-reward playstyle. By mastering her Frenzied state and effectively managing HP recovery, players can maximize Gley’s potential and ensure their team’s success in even the most challenging battles. Whether you choose her as your starting character or unlock her later, Gley is a powerful asset to any team.
