The origin of the megaliths of Geosenge Town has been lost to history, and answers to the question heretofore accessible to Man survive only in legends and local folklore. What is known is that they have long been associated with the rock spirits called Carbink, who are born when rocks are pressed together in the mantle. The Carbink possess a unique ability to connect with the spirits of rocks which never became pokemon, and communicate the thoughts and memories of those rocks' own spirits to the outside world.

Team Flare, which sought to revive the megalith's potential as an ultimate weapon, scoured reflection cave for Carbink in the hopes of learning the secret of its operation, but the overwhelming majority of the Carbink refused. Some claim that one Carbink, facing torture, finally relented and told Lysandre that ancient secret lost to Man, but the Carbink and their trainers insist that Geosenge's secret was found not through the Carbink, but in a forgotten historical document; they claim instead that the Carbink tried to destroy said text when they learned of it, only to be defeated in battle.

Incidentally, it can be confirmed that after the weapon destroyed half of Geosenge City, the crater it created, although too dangerous for trainers to enter, soon teemed with a population of Carbink. A few have suggested that the Carbink of Reflection Cave have begun to recolonize their ancient home, or that the blast was so powerful it freed Carbink from beneath the planet's crust; in truth, by the weapon's own destruction, the Carbink who fueled it were freed from five thousand years of captivity – a fate which may seem worse than death, but is not unusual for these pokemon, and is only a blink of an eye in a Carbink's long lifespan.
