Isabelle is a sheltered child who struggles with magic despite the large Mark of Handling on her shoulder. Daughter of Vadalis House head Dalin d'Vadalis, she was often pressured by other higher up family members to perform tasks that was difficult for her prior to her mark appearing. This bullying continued until she was thirteen (13) when it stopped abruptly. Isabelle holds nightmares to the event that took the bullying too far, but the House maintains that nothing actually happened that day on all paperwork, making her believe nothing actually happened. Around the same time her mark appeared, and, while it acts aberrantly, it was a true Mark of Handling.
Isabelle growing up had only a few friends - her cousins Scilla and May along with her friend Ria, who was a first generation Mark of Handling woman that was added into the House in the last decade. Under their urging, she looked into ways to supplement her lack of magical control. Landing on magitech, she studied equally biology and engineering. Now pioneering a new chapter in House Vadalis towards bio-magitech-engineering she hopes to find ways to aid animals and humans.
Her current projects include magitech beasts, currently by the name of Argan, Riar, and Echo, that allow changes of longer lives for pets and efficient protectors for families and personnel, along with Mark Resonators that are meant to reduce pain and damage dealt by aberrant marks.
Isabelle holds feelings for Jasmine Glayder, and some for Arishtava, however she keeps those on reserve, believing those two are better together. However, she recently has gotten on decent terms with Narcy of Xandrar and may or may not be catching feelings for the archmage...
