Introduction

A system of five low mass red dwarfs, including one of the lowest massed red dwarfs known, little interest other than early research into low massed stars was ever paid attention to this group.  While close to the Sol System, all the stars nonetheless remain far too dim to observe without aid, and little was discovered that garnered much interest in the scientific community as a whole for several hundred years.

Gliese 643 itself is the second dimmest star in the system, and is entirely unremarkable as far as red dwarfs go.  One item of interest that made it (and its companions) stand out above most other red dwarfs is that it is not a flare star.  There have been no observed flare eruptions since observations were first commenced back in the mid-Twentieth Century.  For some scientists, this made it and its higher massed companions possible places that tide-locked, Vesperian worlds might be found.

The primary world, named Dunwall, turned out to be even more remarkable than that, for it was an almost textbook example of a Bishop ring megastructure.  Discovered by an expedition from the League of Worlds, during a period when all surrounding stars of Sol were being explored, chartered, and colonized, it opened up a brand new chapter into our inhabited Milky Way, billions of years ago.  While  much of the world was abandoned and covered with wild ecosystems, there were regions that still held the carefully preserved ruins of the Dunwalli race, some of their technology, and many of their records.
