Penteractic crystal are first mentioned by Dr. Helix Helix, who states that it is a necessary ingredient for the Sands of Time that will prove vital to accelerating his research into the Secret of Evolution. The doctor sends Psaro, Rose, and Toilen to the Lower Echelon of the Circle of Caprice to find the penteractic mine, where the trio encounters a horde of stone golems excavating the crystals.
During the journey through the Middle Echelon, Psaro and Rose would learn that these stone golems are the slaves of the wicked Petrarch, whom he has extract the crystals from the mine in the Lower Echelon. He works the golems till their bodies crumble under the strain of their toil, and then restores their forms so that they must continue working forever.
Much later, after the confrontation in Aamon's Sanctum, it is revealed that the Circle of Caprice is the Queen of El Zetta, the long-lost kingdom of the elves. The Queen explains to Psaro that Aamon desired the elven magic to manipulate time and space, which the El Zettians had condensed and materialized into the twin crystals travelite and chronocite. He led a raid on the kingdom and cursed the elves to become his stone golem slaves and then turned the Queen into an entire landmass, which he would drag underground to Nadiria to become the Circle of Caprice.
Though not stated directly it is implied that the penteractic crystals are the fragments of the larger chronocite crystal, thus explaining why penteractic crystal is the key ingredient to creating the Sands of Time. Furthermore, it is possible that chronocite is what powers the Secret of Evolution itself, as the occult mechanism is the rapid acceleration of evolution applied to a single being. This would explain why Aamon dedicates so much to the continued excavation of penteractic crystal, giving him ample material to experiment with and discover the mind-rendering flaws in the transformation.
