Wren was born the daughter of Andras to mother Shaba and sister Iris in the eastward land of New Bayridge; home to the Black Eagles, a prosperous empire. Andras was a warlord of twisted morality, and while his daughters came to him in many prophecies whispered to him by God, they were never meant to be daughters. An unspeakable childhood then led to a violent uprising, and in the midst of the fray, Wren lost mother while sister and father remain at large.

Her arrival to the Teekons came shortly after her second birthday in the spring of 2023, where she flitted about with few goals until she reached Swiftcurrent Creek. Though brash and impulsive, her dedication led her from iota to gamma under the leadership of Akavir and Arric, with plans of ambassadorship, mercenary training, and becoming beta alongside them. She found a blossoming fondness for Silvertongue; a leader of allied Riverclan.

In the autumn, disaster struck the valley. An old enemy drove Silvertongue away; a spat between creek and stone circle drew the final straw from Wren. Now lost and morose with heartache, she returns to square one — reckless, bitter, and lacking in direction.
