Tkon Nanosphere
The Tkon Nanosphere was a probe-like device built by the ailing Tkon Empire 60,000 years ago. Built on Dovek II, the device was intended to be used to seed specialized nanites into the atmosphere of that planet. The device was comprised of several high-density alloys, including iridium. It was powered by an unknown power source that emitted chronitons and seylerions. This allowed the device to create a temporal vortex through which it could travel through time and space. Those nanites would then begin the process of breaking down high-energy radioactive particles that were bombarding the planet from the remnants of the supernova that destroyed the Tkon Empire. It was designed and created by the Tkon scientist D'askto. The sphere was controlled by a complex Advanced reasoning network , known as Adrene. It was built by D'askto by using his own neural engrams as a basis. Its purpose was to allow the device to learn, adapt and adjust it's actions on-the-fly.
In 2414, the Borg sent an expedition to Dovek II led by a drone named Volus. His mission was to locate and recover the ancient device with the hopes of using it to seed nanoprobes into a planet's atmosphere, thus accelerating the process of assimilation.
Volus was a firm believer in Borg philosophy and, as such, was granted a great deal of individuality by the Borg Queen. Only the arrival of the USS Boudicca and the USS Rosenante prevented his success.
The Tkon Nanosphere was first seen in the joint USS Boudicca and USS Rosenante mission Once More Into The Breach
