Moonbiter was one the Ten Who Were Taken. He or she did not have many interactions with the Black Company and the information regarding him was scarce. His Barrowland sigil showed a werewolf. Moonbiter played a role in the defense of the The Tower during the Battle of Charm against the armies of the Rebels commanded by the Circle of Eighteen. On the same night that Nightcrawler was reportedly killed by Rebel action, the Faceless Man and Moonbiter were said to have been killed, "consumed by feud among the Taken", and possibly by one another. Moonbiter was not heard from again, and the report of his/her death is presumed to be accurate.

Years later, Black Company veterans Otto and Hagop would take a fourteen-thousand-mile round trip to gather information in an attempt to learn the identity of Longshadow, and to return to the deep south with their findings. They reported that everyone in the north was certain that the Faceless Man, Moonbiter, and Nightcrawler were indeed killed at Charm, despite the fact that no bodies for any of the three could be found.

If Moonbiter was female, it would fit The Lady's claim that the women among the Taken were betraying her in support of the Dominator. The Faceless Man would have died defending The Lady against the traitor Moonbiter, just as Bonegnasher died fighting the female traitor Stormbringer days earlier.
