A member of the Enterprise crew, Ensign Syl was serving aboard the ship in 2263 when it was destroyed by forces under the control of Krall. Syl survived the attack, and was given the ancient Abronath weapon by Captain Kirk for safekeeping. She hid the device inside her head, where it remained until Krall threatened to kill Lieutenant Sulu. She surrendered the device in return for Sulu's life, and was subsequently murdered with it by Krall. [1]
