Praesidius Sector includes all the armies in the Warhammer 40,000 3rd Edition rulebook and codices and more. Some of the armies used in our campaign have been created by gamers and extensively playtested to create a balanced codex. The following codices are ones that have been created by gamers and are currently being used in Praesidius Sector.
More races and armies may be added as they appear in the sector, but these are the only ones currently being used. Note that these codices are not official and that you should get the agreement of your gaming group before you use them in your campaigns.
