Past the Edge of Darkness
Lord Militant Angevin conquered the Calixis sector more than one thousand years ago. One of the Northern most sectors of Imperial space. Very distant from Holy Terra the Angevin Invasions secured the Calixis Sector as one of the last sectors to be taken as Imperial space. It is in the northern most section of the Segmentum Obscura of the known Imperial Galaxy. On the up side, because of it’s placement, the sector is rarely traveled directly by the forces of Chaos Marines and Eldar craft worlds, however, because it is so cut off from the rest of imperial space it has some of the biggest problems with minor alien species and warp corruption as the forces of chaos seek a back back door into imperial space.
