If you need to know how everything--basically--works here, you're in the right place! Some links are provided to things that are vital to know in order to begin roleplaying. But the first step before anything, don't forget to bookmark this site.
In short, you need to know that:The year is 2380. Earth is a wasteland, after its societies destroyed themselves from the inside out.
The Weavers were said to have created the planet Earth. There were four generations of them, and shaped Earth's fields, plains, and meadows, and other planets. They are granted control of the lifelines of the Earth, the leylines, and its elements. These abilities are passed down in descendant bloodlines later. The second generation of Weavers soon after arrives, shaping the mountains, deserts, canyons, and plateaus. The third is the intellectual generation, shaping early beliefs. The fourth is a wild card, and is comprised of those with brilliant psionic abilities of the mind. (i.e. telepathy, telekinesis, kinesis, etc. ) Any "Weaver" after this, is classified as magerath, a different bloodline. In this way, humans can descend from magerath, Weavers, and z'hadrei if their ancestors had children between the races over time.
Half-bloods are those of human and mageran blood.
Humans are the czadians' ancestors, as early humans wandered onto Daldrei through means of warp Gates on Earth.
The Republic is the Core Worlds' and Outer Rim's system of government. Corruption is becoming apparent in some sects.
The Alliance refers to any rebel faction or individual against the ideals of the Republic.
Europe and Asia has a strong influence on cities and life in space.
Psionics are powers of the mind. Some accept them, some deny their existance, others do not accept them. Usually such things are known about in public, but not discussed. In order to have psionic affinity, usually the individual--provided that they are a human-- must descend from a generation of Weavers, magerath, or z'hadrei, but in some cases, the human can manifest them on their own.
Anything besides this, and this included, you can learn about in-depth in the
