System information

The Cyrene system was home to at least one habitable world.[1]

System Description[edit]

The Cyrene system is located in the Rimward sector of the Deep Periphery close to the Perseus-Cepherus Cloud Complex.[2]

System History[edit]

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;[3] 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.[4] 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.[1]


The Alexandrian Covenant is detailed within Interstellar Players 3: Interstellar Expeditions, but no map of the state is given - only the location of the Covenant in the Deep Periphery.[2] It is therefore impossible to determine the precise location of Cyrene.
