The vast volumes beyond NGC 6633 and IC4756 in the Serpens Cauda direction is sometimes called the Serpens Frontier. Although the Mutual Progress Alliance expanded into this volume many millennia ago, it has not been systematically explored or settled. The region extends from the Middle Regions outwards towards the Outer Volumes and Periphery; in this region the Periphery is largely unexplored.
The reason is mainly the somewhat haphazard way the Alliance (never a strong federation) expanded outwards and the disruption of the wormholes during the Version War. Due to an accident of transport-political geography the origin of many of the main wormhole links into the region from both the MPA and Sagittarius Sphere were in the vast volumes attacked by the Negentropy Alliance. As the links fell, the whole region was cut off. Due to the slow rebuilding and political uncertainties among the neighbours it has taken many millennia to continue the linelaying projects. Apparently the Keterist cultures to the galactic south have chosen not to expand into the region, keeping below the symmetry plane in accordance with old MPA-Keter treaties.
Recently the Sagittarius Transcultural Cooperation has become very active in the area, extending a number of wormholes into the region.
The region contains many unusual cultures and alien artifacts, various divergent To'ul'h clades, The Cooperative Venture, the Surreal Rash and countless other wonders. Some have expressed worry that there also lurks dangers like the Dawn Hunters or alien or mainbrain nanoweapons from the Reserve.
At present there is great excitement about the Serpens Frontier. A vast volume containing many fascinating cultures and objects is being rediscovered. Many societies that have been isolated for millennia re-connect to the Wormhole Nexus and several alien species will come into contact with the mainstream of humanity.
Cooperative Venture, The - Text by Anders Sandberg and M. Alan Kazlev An interstellar cooperation between the Serpens Region civilisations in mainly archaeology, trying to understand some relics from lost alien civilisations, especially the Dawn Hunters and the Black Acropolis. Other areas are protocols for information and entity transfer, conflict resolution and geography. Main planet Avensis, 545 Manus in the classic Skiiws'nnii astronomy.
Reserve, The - Text by Anders Sandberg and M. Alan Kazlev Volume of space centered around a group of stars apparently involved in an old transcendent civilisation. The volume stretches in a rough tetrahedron from the red dwarf 594-456111, the sun-like stars Alpha and Eta Filiae and the wisp of dark cloud locally called the Mouthpiece. It has numerous terraformed planets teeming with life, but is aggressively protected by both local nanosystems and several Caretaker Gods. What lies inside is unknown.
Upsilon Xiphias I - Text by Anders Sandberg and M. Alan Kazlev Planet in the Serpens sector of the Outer Volumes, inhabited by a decadent and evolutionarily static heteromorph tweak clade, the Old Fogeys, who are served by turingrade vecs. The Old Fogeys are likely left from one of the Inner Sphere systems during the Age of Expansion, but records that might confirm this have been lost.
