This relatively small relic was discovered on Mars in 2280, measuring no more than a few centimeters square. Indeed, there is so little concrete information in the public sphere that some have questioned the Relic's very existence. But leaked Federal records confirm that the object, which was sequestered by the Federal government shortly after its discovery, is very real.
The discovery of the Unknown Artefacts, Unknown Probes the mysterious wreckage in the Pleiades Sector AB-W B2-4 system, and the Ancient Ruins discovered in SYNUEFE XR-H D11-102 system has prompted many to wonder anew at the Relic's origin. Naturally, some have speculated that it could be a Thargoid artefact, but with access to the Relic restricted, this theory can be neither proved nor disproved.
Until the Federal government decides to release information into the public domain, we can do little more than speculate.
