A large shaggy beast renowned for its uncanny ability to escape almost any effort to confine it. The cow-oc closely resembles a Terran cow except for the two prehensile tendrils that attach to top of its skull, just behind its ears.

The tendrils are often the same colour as the cow-oc’s coat, which ranges from a dull cream through to dark brown.

Cow-orcs are reliable animals with a calm, steady nature. Little seems to worry them, which made them very popular as beasts of burden and for over a century they formed the backbone of the freight/transport industry. However, with the increased availability hovers and shuttle, their popularity has waned, and now there are only a handful of studs that continue to breed this under appreciated animal.

Earth-Jørn hybrid specialisations

Originally designed for a particular purpose, every species of Earth-Jørn hybrid can still be classified not just as a strider or flyer (and their attendant sub-categories) but also by their job/specialisation.


Note that a species specialisation is independent of its classification as either a strider or flyer, and that while a species can be suited to many purposes, it is usually ideally suited to just one.


Fast and agile, scouts were designed to be intelligent animals capable of independent thought and action while remaining loyal to their handler. These same traits can make them difficult to work with for handlers who are inexperienced or unconfident.

The first scouts were created to accompany Riders on the surface to scout ahead, relay important information and map the terrain.

Most scout species are flyers. They include the linch-adder and oad-hawk.


Versatile and hardy, an explorer’s primary attribute is their ability to adapt to  any situation or environment, and survive. Most explorer species are inquisitive, athletic striders, capable of going long distances and defending themselves against large predators.

Explorer species include ruc-pards, toa-mares and sterdanes.


Guardians are fierce, predatory and loyal. Large and small, they are defined by their ability to defend a person, object and/or location. 

Dober-shepherds, used mostly by police, are the most common guardian species.


Large, strong and hardy, haulers are beasts of burden, designed to move cargo from one location to another. Although still common in ground side installations, they have been replaced by motorized transport in the cities.

Hauler species include cow-ocs.

Search and rescue

The search and rescue species are the most specialised. As a type, they are calm and highly intelligent with exceptional sight, hearing and sense of smell. Many of them hear and see in ranges far beyond that of humans and even other hybrids.

Sternards are the most successful of this type.


Like scouts, racers are built for speed and agility, but without the same demand for independence and intelligence. The racer specialisation is the most recent, spurred on by sports such as barrier racing.

Doe-ocs are a popular species of racer.


A companion is an Earth-Jørn hybrid animal that is similar to a pet, but forms a closer bond with their human than the typical Old Earth cat or dog.

The term was coined by the first-gen Rider Beatrice Shrew to describe her relationship to the two animals (a ruc-pard and a flurry-thyt) that helped her explore the Jørn wilderness. Beatrice found the terms ‘pet’ and ‘mount’ grossly inadequate to encompass the mutual respect and cooperation that existed between her and her companions, and which was so necessary to their survival.

Instead, Beatrice described the relationship as a partnership in which they all had a role and relied on each other to do their part, and through which they became more to each other than just a friend, but an integral part of their being.


A category of Earth-Jørn hybrid. All species of flyer are capable of flight and typically feature a large percentage of avian or insectoid genes in their makeup.

Most species of flyer are bred as pets or found in sports such as barrier racing.


Flyers are classified according to their:

  1. wingspan
  2. typical flight distance
  3. speed and agility


  • Midget
  • Small
  • Midi
  • Large

Typical flight distance

  • Short-distance
  • Long-distance

Speed and agility

  • Rocketeer
  • Cruiser


A land-based Earth-Jørn hybrid animal, typically over 120cm high at the shoulder and capable of carrying a full-grown human. The roomal was the largest amongst the strider species, while the turt-sheep remains the shortest.

Developed by the human colonists as beasts of burden and as a food source when their Earth-born spieces succumbed to the Pollen, striders are the most common companion animal.


Strider spieces are divided in several different classifications, based on weight, height, strength and hardiness. These classifications are:

  • Mini strider
  • Light strider
  • Mid strider
  • Heavy strider

Beasts of burden

These striders, such as the ruc-pard and toa-mare, were initially developed to carry people and goods across long and often hostile terrain. Species that fall into this category are generally over 130cm high at the shoulder, intelligent and hardy animals.

Food source

Although species in this category can, and have, been used as beasts of burden in the past, they were developed primarily as a food source. Species in this category include the wombacow, turt-sheep and por-ig.


Fink flipped his thick, hairless tail, letting it land with a solid thwack on the deck not two feet from the tips of the woman’s shoes.

The Lamb stopped, her gaze locked on Fink.

It was hard to tell which characteristic people found most intimidating about him. It could have been the teeth, the claws, his sheer six-legged bulk or it could have been the reputation, the stigma of a species mixed in a lab by not just a crackpot but The Crackpot, by Woolsey.

…No one else would have thought to mix a little bit of rat with a little bit of leopard and a whole lot of rucnart to create something big and strong and scary enough to walk the surface with impunity.


Classification: Heavy strider.
Specialisation(s): Exploration.
Breeding Status: Retired from the program. Breeding successfully in the wild.

Weight: 600-800kg
Height (at shoulder): 1.4-1.9m
Length (nose to tip): 2.8-3.9m
Genetic combination: Rat (Terran), leopard (Terran), rucnart (Jørn)

Arguably the most famous of Dr Augusta Woolsey’s creations, ruc-pards (‘pards) are among the more distinctive Earth–Jørn hybrids, with six legs, a leopard-like body and rat-like forequarters, head and tail. Although huge in comparison to other companions (with the exceptions of the roomal and slale-bear) fully-grown ‘pards still cannot match the size of their native Jøran cousins, the rucnarts.

Known for the ferocity and hardiness, ‘pards are capable of taking on all but the largest of Jørn’s indigenous species.
Today, the ferocity and intelligence that made them so valuable to early explorers has become a liability in the closer environments of the cities. Coupled with a fearsome reputation and the stigma attached to all of Dr Woolsey’s creations, their popularity as companions has declined and they are rarely seen outside of the Farm.

Ruc-pards are one of the few Earth–Jørn hybrids that thrive in the wild, and the Farm keeps track of over thirty-eight packs scattered across the globe.


…to a girl with a linch-adder wrapped around her neck.

The ‘adder was easily the length of Hero’s arm, its breast covered in purple feathers that tapered into the yellow scales of its belly and a long, sinuous tail; it mantled its green wings and hissed at the sight of Fink.


Classification: Midi-flyer (short-distance Rocketeer).
Specialisation(s): Scout.
Breeding Status: On the program. Licenses for external breeding available.

Weight: 3-5kg
Height (at shoulder): 35-50cm
Length (nose to tip): 90-110cm
Wingspan: 100-130cm
Genetic combination: Adder (Terran), finch (Terran), linkal (Jørn)

The linch-adder, or ‘adder, is a mid-sized flyer first engineered as a scouting companion for Riders.

Its loyalty and fearless disposition made it a popular companion animal for Riders and other personnel going ground side, where is was known to harry and drive off much larger animals. However, the ‘adder’s slow maturation, from hatchling to adult (eight years), and its difficultly to train, soon saw it replaced by faster growing and more biddable species, such as the oad-hawk.

The ‘adder remains popular among those looking for a more unusual companion animal as well a select few trainers and ground side personnel.


“The first barrier is coming up.”

On the inside of her helmet, the view changed, a diagram of a semi-transparent wall, a round hole in its centre, overlaying the skybridge. “What is it?”

“A modified shock skin. You have to jump through the hole.”

“I thought this was meant to be hard?”

“It is.” The feed from Harish’s harness grew large on her holo-screen, and she saw a flurry-thyt hunched over a switch. “Unless the switch is down, there is no hole.” An oad-hawk knocked the ‘thyt from its perch, and a doe-oc slammed into the space where the hole had been. “But don’t worry, Harish knows what he’s doing.”


Classification: Light strider.
Specialisation(s): Racer.
Breeding Status: Currently being bred outside of the Farm’s program.

Weight: 300–500kg
Height (at shoulder): 140–170cm
Genetic combination: Deer (Terran), ocupline (Jørn)

A variant on the disastrous doe-rahm, the doe-oc has become popular among barrier racers. Renowned for it’s speed and agility, it is ideally suited to the sport but, with the same vulnerability to the Pollen as it’s predecessor, is not viable for ground side work details.

The first companion species to be engineered outside of the Farm, the doe-oc represents a new era in companion breeding. While the P’Tember stud, who produced the very first doe-oc, continues to be the leader in non-Farm breeding, several other studs have sprung up in its wake.
