The Universe is full of stuff. This category includes the sort of stuff which we as the players of the ISA Phoenix game thought was interesting or important enough to merit an entry in the wiki. This category will be expanding as the wiki continues to grow beyond an archive of logs.
Items can be designated as "canon" -- meaning they appeared in Babylon 5 or Crusade canon sources, most typically the TV series or movies themselves but also some of the novels. The To Dream in the City of Sorrows novel, which focuses on the Rangers, is considered canon.
Items can also be designated as "non-canon" -- meaning either they appeared in a non-canon source (including most of the novelizations or the Chameleon Eclectic or Mongoose Publishing RPGs), or were invented by the players ourselves.
