Babylon 5 is also one of the better SciFi shows to hit the air. Personally it is my favorite. As B5 has a lot more story and background, I feel as if the order of the synopsis should change a bit. The Races: Centauri - They look very similar to humans,except the big hair which looks quite awesome. Long ago, the Centauri were a very powerful and large republic. The expanded their nation over a great deal of the galaxy. Eventually the Centauri's conquered a low-tech world known as Narn. The habitants of Narn proved to be great nuisance. As soon as the Centauri's stripped the world of its resources left the Narns alone, to their desolate home world. This is where fall of the great Centauri empire started. Narn - The Narn are a large, physically strong reptilian race. After the insurrection on the Narn home world, the Narn's were furious. Their once beautiful, even Oasis like planet was destroyed and barren. The Narn's, being who were very vengeful, took it upon themselves to destroy the Centauri. The quickly rebuilt and terraformed their home world, and with the technology they learned from the Centauri soon set off into space. Eventually the expansion was brought to a stop by the Dilgar, and from this are a much weaker race then the Centauri. Minbari - A very old intelligent race, that has been a space-fairing race much longer the either the Humans, Centauri, or the Narns. They also are much more technologically advanced as well as more powerful. They Minbari are split into three difference sects. The Warriors, the Religious cast, and the Worker class. Their leading body, the Grey Council is made up of nine members, three from each class. Valen the first great leader of the Minbari created this Council, and all three casts look to Valen as the greatest ever leader of the Minbari. In almost every recent galactic conflict the Minbari has stayed neutral. Vorlon - The oldest race out there, yet almost nothing is known of them. No one has ever entered their territory and ever came back out. No one has actually ever seen a Vorlon either as they walk around in an enviro suit. The one thing that is known they are far more technologically advanced than any other race out there. Humans - Just until recently was a non-space fearing race. The Centauri assisted man and with technology and weapons, but they still were not a major player in the game. They were pretty much unknown until they decided to help the allies against the Dilgar. For most part they were turned the tides of the war, and eventually wiped the Dilgar out. The League of non-aligned worlds - Consists off a bunch of smaller less powerful races. For most part don't play a big part in the big picture, but are mentioned from time to time. For further purposes will be called The League.
