One of a trio of Precursor artifacts whose mystical link to each other has been sensed by Pkunk psychics, given simple names based on their color and shape. The Aqua Helix is a crystalline gemstone, composed of a homogeneous substance, that appears to have been naturally grown in the shape of a flat strip twisted in a three-dimensional spiral. It is extremely hard (rated Mohs-13, able to scratch a diamond) and its internal structure remains unknown. The Thraddash revere it as a holy object, and constructed a shrine for it in a mountainous cave of the continent of Funt on their home planet of Zeta Draconis I. While housed there, the Helix constantly gave off pulses of intensely bright light by an unknown process; control of the shrine and the Helix was regarded as the ultimate symbol of the ruling authority of each successive Culture, and within the shrine was inscribed in ritual hieroglyphics the history of each Culture. This custom has lasted for all 2,000 years of Thraddash history, only briefly challenged by the two-week reign of the heretic Culture Nine. Except for that one exception, the Thraddash dogmatically insist on veneration of the Helix as the one constant factor that keeps their civilization continuous through all the countless wars and power shifts that make up their history, despite the fact that the Thraddash have long forgotten what the original symbolic significance of the Helix is. (Some speculate its helical shape may be related to the Thraddash's conviction that social evolution must come through a cycle of destruction and rebuilding.)
The ascension of Thraddash Culture Twenty, based around the teachings of the human Zelnick, led to an invitation by the Thraddash to allow their new leader to view their most sacred artifact. Having learned something of the Helix's nature from the Pkunk, the Captain allowed his crew to violate the Thraddash shrine and steal the Helix, disturbing its structure and quelling its ancient glow, causing the Thraddash to turn against their great Teacher, throwing Culture Twenty into turmoil. This decision however proved wise, as the Helix proved to be one of the parts necessary to repair the Utwig's Ultron.
