A Klingon woman serving under General K'Vagh who takes part in the covert operation against Enterprise and is herself changed by the Augment virus.
Laneth appears in Affliction and Divergence. She is one of the officers working for K'Vagh while his scientists at the Qu'Vat colony struggle to stop a plague created by experiments with human Augment DNA.
She is part of the Klingon force that boards Enterprise to plant a subroutine in its engine systems, a piece of sabotage that later forces the ship to hold dangerous speeds to avoid a reactor breach.
Like many of those exposed, she loses her cranial ridges, and makes plain her disgust at coming to resemble a human. She is present as Phlox and Antaak race to produce a cure before Fleet Admiral Krell's ships sterilise the colony.
