An artifical space feature of unknown purpose: a single, apparently dormant, device has been found in an empty star system within the Delphic Expanse. All efforts to dismantle and study the feature have proven fruitless and the sudden unexplained disappearance of a few investigating teams adds to the mystery surrounding the device.

Who made the feature, out of what and how does it operate are all unknown as is the actual function. Now abandoned and rarely visited, especially since it falls within a particularly lawless area of the Expanse, the large artificial construct eludes understanding.
