Here is the current and updated 2014 Faction list :
Adrifell -
The long extinct Adrifell are the creators of the Etherium Universe. As their own universe was nearing it's natural end into the heat death phase, the Adrifell built an enourmous Hadron Collider that could create a custom God Particle which would give birth to an artificial universe that they could live in. They suceeded, but the Etherium was an imperfect entity with many faults. Relics of Adrifell Civilization can be found all throughout the Etherium on thousands of worlds.
Karuthrax -
The karuthrax were the First Error to emerge within the Etherium Universe after it's Hadron Collider birth, a Universe that was never meant to evolve it's own lifeforms, somehow evolved a mass of sentient micro pocket-universes which have developed cosmic consciousness and have psychically linked themeselves together to form a culture of some sort. They fought a long war against the Adrifell, which resulted in both species eventual extinction, giving way to a new age with less powerful species.
Tolathians -
The realm of the Tolathians is a large, cell based commune empire that is overseen by the Thane of Tol. Tolathians are a mystical, powerfull, wise and elemental species which believe in traits such as fairness and loyality. They often protect and defend the weaker species and ally with the Iaethien and Cascadians to name but a few.
Luuran -
The Luuran are a species of religious zealots, corrupted by fallen Karuthrax and Adrifell technology - they have become a nemesis to the Etherium, reaching their talons into other species, launching crusades of faith, becoming an enemy of logic, reason and science. The Luuran's imperialist ways have earnt them a terrible reputation across the Etherium.
Masters Of Unlife -
They are Anti-Life itself. From some ancient beyond imagining realm, beyond the sanity of space, time, dimension and reality - lies an anti-existence, a place no eye shall ever see. The place of Anti-Life itself, the dreaded Masters of Unlife come. The minions from the plain of Anti-Matter itself ; dreaded abominations which create swirling Black-Holes to explode into the reality of space in order to do nothing but wipe out all life for insideous reasons that which will never be known.
Cascadians -
The Cascadians are the servants of the living Time-Vortex. Each entity can co-exist with hundreds of it's own selves due to each inhabiting it's own time-bubble. They are masters of chrono based weaponry, guardians of past, present, future and allies to the Tolathians and Iaethlein.
Psylorthion Conflux -
The Conflux are a species of artificially created beings made from a strong resiliant metamaterial that is able to withstand extreme temperature and weathering, making them hardy and strong but with a fast decay-rate. The actual minds of the Conflux are sentient datastreams which live within singularities on planets called Anchorworlds.
Iaethlein -
The Iaethlein are a species of Energy beings that inhabit hard-holographic armoured shells. A unique trait of the Iaethien is their empire which is a vast array of Dyson Spheres connected together into one enourmous cosmic circuit. A unique aspect of Iaethlein technology is how their brains work - they can partition a part of their holo-bodies and slow the light down to an almost static state, allowing complex arrays of signals and patterns to exist in order to create an advanced mind with mass-storage capacities beyond any organic beings.
Calixyren Syndicate -
The Calixyren Syndicate are a civilization based on one of the Adrifells strange cosmic equations. In effect, the Calixyren are a culture of living sentient mathematical formulae. Due to them being such a core component of the Etherium, they are highly guarded, cautious, defensive and isolationist.
Exorphiens -
The Exorphiens are a race of living paradoxes living in conjunction with each other - allowing each one to exist together. As such the empire is named the Exorphien Conjunction.
Quartoulians -
The Quartoulians are the remnants of a living reflection of a universe simulation discarded aeons ago by the Adrifell. The Adrifell did not expect their universe simulation to have a reflective shadow to it, but somehow once the simulation was disabled - the reflective shadow of it still remained and evolved.
Halaedion Talons -
Evolving on the firey planet of Asaag, the Halaedion are the physical avatars of a vast magnetic pull between two enourmous worlds, that for whatever reason developed a consciousness, perhaps due to the complexity of the magnetic wave between both worlds. The magnetic wave was able to use it's pull to piece together automatons for itself that it could use to explore the Etherium and learn and discover it's purpose - and these became the Halaedion.
Ylataran Nexus -
The Feared Nexus are an immensely powerful species which have seemingly conquered millions of universes, converted the mass-energy of each and used it to increase the power of their own biological and quantum extra-reality. The Nexus seek to make themselves the masters of the "Existiverse", or outer-universal shell from which all other universes reside within, so as that they can break down the very walls of existence itself and see what lies beyond. They possess reality altering weaponry and ships which are dimensionally transcendental - allowing them to insert entire legions unknowingly into whole worlds and galaxies. They have now arrived in the Etherium.
