Sagittarius Dwarf Elliptical Galaxy (SagDEG) - Text by M. Alan Kazlev This minor galaxy has been spread out by a still on-going collision with the Milky Way. The closest parts of this remnant have been colonised by the Red Star M'Pire.
Sagittarius Dwarf Galaxy (SagDIG) - Text by M. Alan Kazlev M 31 / NGC 598. This minor irregular galaxy is located at the opposite end of the galactic core to settled space. The Sagittarius Dwarf Galaxy is approximately 10,000 light years in diameter, and roughly spheroid in shape. It is adjacent to, possibly colliding with, the base of the Outer Arm. Relativistic exploration missions have departed for this galaxy but are not expected to arrive for many tens of thousands of years.
Sagittarius Outer Volumes - Text by M. Alan Kazlev Extensive region of space coreward of the Sagittarius Transcultural Cooperation and MPA space, popular with development and strategic interests because it is seen as the gateway to the Sagittarius Arm.
Sagittarius Project - Text by Anders Sandberg Major exploration project backed by a number of research and colonization megacorporations in the Establishment and early Consolidation era. The Sagittarius Project attempted to set up wormhole links to the Sagittarius arm and continue inwards to the galactic core. Over time, the Project developed into a megacorp-house like most others (eventually becoming the Sagittarius Sphere), and the thrust towards the core was replaced by exploiting the many new worlds found in the Sagittarius arm. Some research vessels are still on their way towards the core, and are expected back in a few millennia.
Sagittarius Sector - Text by M. Alan Kazlev Also, "Sagittarius quadrant", loosely defined region that encompasses much of the coreward Outer Volumes. Also known as "The Corewards".
