The Sextans I (Also called the Sextans Dwarf Spheroidal) galaxy is a satellite galaxy of the Milky Way located 320 kilo-light-years from the Milky Way. The galaxy is home to various species capable of creating warp bubbles. These species are called the Pestelentia, named for a particularly damaging species called The Pestilence. The Pestelntia are used by the natives of the galaxy as a means to power their ships. Currently, the five major nations of the galaxy and most of the Thirteen Tribes are part of the Confederacy of Borealis.
The galaxy has mostly been left alone due to its large distance to other satellites, so the few civilizations that have conquered the galaxy soon found themselves having to contend with the ancestors of the Pestilence species, which were still very dangerous even before their domestication. The small galaxy has almost always been not worth the trouble of conquest.
