The Outer Frontier

The Periphery is the ever-expanding wavefront of Terragen exploration and colonisation. It is in fact the furthest layer of the Outer Volumes, beyond the furthest wormholes. Because the speed of expansion of the Wormhole Nexus is limited to 0.7c, there is a large ring-shaped section of the Explored Galaxy that is not yet connected. Only the fastest exploration and colony ships have reached this far.

The location of the Periphery changes over time, as the exploration wavefront moves ever farther out, and the Wormhole Nexus expands over time. But the exploration wavefront is moving faster than the expansion of the Nexus, so the Periphery is getting gradually larger over time. In some locations small, independent wormhole nexii have been created, not yet connected to the main nexus. Some of the oldest of these independent networks, like the Lirantiq nexus, have been connected to the main network and are now in the mainstream civilisation.

Periphery worlds can only be reached by taking a stargate to the furthest system out, then obtaining a relativistic ship (by building one, buying one or receiving one as a gift; rarely by stealing) and making for the unknown. Of course, there will always be someone who has gone further, but the periphery is so vast that there is enough for everyone. Some ships are headed for the galactic core, or the globular clusters, or even aim to leave the galaxy entirely. Many of these have abandoned their quest and established colonies at the edge of the Terragen Sphere.

There have been several major wars on the Periphery in the last millennium or so, but the only one that is generally known as the Periphery War is the one between the Arion Ascendancy and the Periphery Pact.

Cybyotan world in the Vela-Puppis border periphery. The alien Cybyotan phylum of interconnected mobile and sessile autotrophs and heterotrophs has on this planet developed a single shared datasphere which is home to a single entity, known as Clive.
Cygexpa Outer Volume - Text by Steve Bowers
Region to spinwards of the Cygnus Middle Regions, outwards of the Deneb Plexus. Also the region where the merchantile archailect Lohengrin is currently most active. Notable for the presence of xenosophonts such as the Muuh enclave around Muuhhome, the Meistersingers and the Wayfarers.
Cygnus X-1 - Text by Steve Bowers
High mass X-ray binary star system 5984 ly from Sol.
Daemons of Sidene - Text by James Ward
In 9923, the Sidene system, located in the Periphery, fell victim to a fleet of highly advanced ultratech warships. For several years this was the extent of knowledge on the subject, but in 9948 another system, Adice, was attacked and managed to send information to other systems. The local powers have pieced together what they can.

Eta Carinae - Text by Chris Clowes
A binary star system comprising of a peculiar, erratically fluctuating Luminous Blue Variable and an O-type supergiant star. One of the most luminous stellar objects of our Galaxy.
Golifa Nebula - Text by Steve Bowers
Artificial nebula, formerly the Golifa Triune, three stars in Perseus which were destroyed by a Metric bomb during the Amalgamation Crisis
Historical Diaconcentrism - Text by M. Alan Kazlev
The tendency for the peripheral regions to be historically and technologically backward - "living fossils" - in relation to the inner sphere (owing to the amount of transit time - usually many centuries - required to get there). Moving from the core to the periphery is in a sense like moving back in time. This phenomenon breaks down as the outer volume worlds develop their own cultures and civilisations.
Immanentization Crusaders - Text by Anders Sandberg
Keterist extremist group active in a number of regions throughout the Outer Volumes. Their stated goal is to ensure the continued growth and evolution of galactic culture towards the highest possible levels by forcing static and counter-progressive cultures to face the "creative destruction of evolution". They have not been averse to attacking any cultures, civilizations, and polities which they do not consider fit.

Wild Frontier - Text by M. Alan Kazlev
The romanticised and mythologized notion of the frontier, whether the outer solar system of the Solsys Era or the Outer Volumes and the Periphery today, as an exciting and lawless place. See also The Wilds.
