"if there is a purpose...if there is a design...if there is a way...after I'm gone, I will call to you...and say your name...and send you a message. And you will know I was right."
- – Isabelle to Galen
The product of a union between her techno-mage mother Burell and a non-mage, Isabelle spent most of her early life as Burell's apprentice - a common method for techno-mages to acquire an apprentice.
Isabelle and Galen shared a brief but intense relationship toward the end of 2258. Though the two were only involved for a short time, they developed a relationship in which they could speak volumes to one another without saying a word. As Galen would say of her "She would make you happy with one word, hello" Her abilities were as a techno-mage were at least on level with Galen.
Shortly after her initiation as a Techno-mage, she was partnered with Galen in an assignment to gather evidence of the Shadows' return by tracking the movements of their allies on her home world of Zafran 8.
She had long believed that the Well of Forever existed, lost in Hyperspace. To celebrate their first Winter Solstice together on December 22, 2258, Isabelle gave Galen a present and toasted the Well of Forever, a tradition that both her and her mother would partake in annually, with the statement, "Next year, we find it."
Not long after leaving Zafran 8, they traveled to Brensil 4 where they met with Elizar. After many attempts at convincing the two that there was a conspiracy within The Circle that they knew about the Shadow threat, Tilar who was a rogue Techo-mage appeared to them and proceeded to open fire at the two loyal Techno-mages. Isabelle was dealt a mortal blow by the rogue Techno-mage Elizar. Soon after this, she succumbed to her injuries and died. Just prior to dying, she reassured her distraught beloved, that if there was a way, that she would contact him from the afterlife.
Her body was returned to The Circle for burial.
