Located in the Yugumo Cluster, the Siren system was once claimed as a member world of the Yamatai Star Empire and later the United Outer Colonies until their dissolution. The strategic location was then jointly run between both Yamatai and the Lorath Matriarchy in an uneasy partnership in YE 36, but later returned to full Yamatai control with their disappearance in YE 39.
A very special planet with a metallic core primarily comprised of iron encased by silicon carbide and titanium carbide. Mountains of diamonds and a surface of thick graphite covered with rich hydrocarbon atmosphere. There was once a bio-dome-enclosed Peacekeeper facility, called Mayer Station, a few miles outside Siren Mining Colony 7 that once housed the main offices of the Peacekeeper Forces' 4th Logistics Fleet. However it is now only a large crater; its reactors were deliberately overloaded after it was overrun by the NMX.
With the return of many refugees and Peacekeeper Heavy Industries, the local commodities-based economy has begun a revival and expansion. Though there have been unconfirmed reports of multiple Abominations sighted near Colony #4, halting progress of their new diamond mine.
A massive asteroid field forms a shell around the system that is the home to the largest mining operation in the former United Outer Colonies. In the past, Motoyoshi Fleet Yards had both manned and unmanned mining operations in the field, which have now been taken over by its successor, Peacekeeper Heavy Industries. This location is particularly of interest, as it is the only place to harvest the rare elements required to make the patented Sitearium and Stellarium advanced stealth coatings.
PHI is also in the process of constructing a starbase using local materials in the asteroid field (estimated to be completed sometime in YE 38), which will be home to their impressive ex-Peacekeeper private security force. Basing it in the jointly run space avoids the current YSE legal restrictions on a standing military force and allows for relatively free movement through the two nation's border territories to help perform its stated mission of escorting United Manufacturing Cooperative & Lorath Matriarchy assets.
Hundreds of PANTHEON's Eye Covert Sensor Probe units are scattered throughout this area in order to blend in with the asteroids naturally present. They help protect the system by unobtrusively monitoring all cross-border traffic and serving as a very effective early warning system for incoming threats.
