  • Nashorn - Large rhinos used as living tanks by the New Crobuzon Militia. It is not known whether Nashorn are native to the veldt or whether they were imported by the militia during the Tesh-New Crobuzon War.

Found in unspecified habitats[]

  • Pterabird - An undescribed bird-like creature, possibly similar to a flightless pterodactyl. It is used in New Crobuzon as a beast of burden, for pulling taxis, and in unspecified areas of Rohagi for carrying passengers. Silas Fennec mentioned riding one during his journey to High Cromlech.
  • Unhorse - A creature in the shape of a horse, ridden by an Abnatural bounty hunter in eastern Rohagi. Despite its resemblance, it is distinctly not a true horse, but described as a "horse burr under the skin of the real". When the bounty hunter is killed, the unhorse runs into a rock, leaving "an animal-shaped bruise of lichen".
  • Wind-polyp - A floating polyp-like creature that thaumaturgically propels itself through the air with the help of flightglands. Their flying motion resembles a flower that opens and closes, releasing small jets of discoloured air.

Found in the Fractured Land[]

  • Slake Moth - A highly intelligent predatory creature that feeds on sentience. It exists in several planes simultaneously, making it difficult to kill.

  • Lahamu - Also referred to as a "cuttlegod". Presumably a species of massive cuttlefish, it is another target of Tintinnabulum's hunter group.


  • Chicken - Both normal and giant chickens live in New Crobuzon and the surrouding Rude Wood. Giant chickens are used by tribal Hotchi as mounts.
  • Badger - Often kept as familiars by the thaumaturges and scientists working in Brock Marsh, New Crobuzon. Badgers are believed to protect their owners from the "dangerous harmonics of hidden sciences", and thus make popular pets and message-carriers.
  • Dog - Both mundane and Remade dogs are found in New Crobuzon. The militia are known to use Remade dogs with thaumaturgicaly-enlarged noses and craniums and mechanically-enhanced senses to track targets across extremely long distances.
