There are no wolves in the Darkhive, so the concept of a werewolf is foreign. But that doesn't mean there is a complete absence of Lycanthropes. The various ships that have landed on the hive brought rats, lizards, ferrets, foxes, and other small predators. The Lycanthropic virus uses what it can, and thus wererats, werelizards and other creatures linger in the shadows.
Lycanthropes aren't considered a menace in the hive, but more an unstable ally in the eternal war against the forces of darkness.
