MA-84 is an M2V star with only one planet with a breathable atmosphere, and it is barely breathable at that.  This is a star which has never attracted attention from the public or corporations as there is little of interest to them, and has thus never even been given a proper name.  That is the reason for its continued use of the scientific classification.
The star's only planet with a breathable atmosphere is the third from the star.  Much of the planet is in perpetual night.  The part of the planet which does have sunlight is still dim. There is little of interest, and almost nothing to mine, however, members of that Universalis Arcanum have recently uncovered signs that an alien race, the Cerritac, once lived here.
