According to Halloway, Fisari was a woman from Malakye who supposedly went missing on a research trip near Briarbreak. It is believed that Shyvana discovered her body in a set of ancient ruins alongside two others. The exact circumstances of her death are unknown, but in the room in which she was found was the entity of blue-grey energy, which may have contributed to her demise.
Before her presumed death, Caylo and Halloway both seem to have known Fisari, although her relationship to them both is unknown. Caylo claimed she had had a power to "know lots of things."
