Cyrene

The Cyrene system was home to at least one habitable world.

System Description
The Cyrene system is located in the Rimward sector of the Deep Periphery close to the Perseus-Cepherus Cloud Complex.

System History
The Cyrene system was colonized at some point after the late twenty-sixth century by the Alexandrian Covenant, a Deep Periphery proto-state created through the merger of colonists from the Magistracy of Canopus and the Taurian Concordat. At its height the Alexandrian Covenant was a nation of multiple worlds that enjoyed a degree of interplanetary trade; however, beginning in the 2700s, the Alexandrian Covenant was engulfed in a series of destructive civil wars known as Upheavals that eventually led to the loss of interstellar travel within the Covenant. The location of Cyrene was identified by Interstellar Expeditions at some point after 3093, but at that point the Cyrene system was uninhabited; IE found evidence of past habitation on the planet and of an extinction-scale level of destruction, but were unable to date the destruction to a period corresponding to any of the known Upheavals, leaving the mystery of what wiped out the population of Cyrene unsolved.
