Astronomical data Edit
Tarron orbited a blue star. It had a radioactive core. It had no native trees, so they had to be grown hydroponically. Its native species were extinct by the time of the human colonists, leaving only a piece of jewelry. (PROSE: Tarnished Image)
Circa 10,000,000, the colonists left Earth for Tarron. Shortly after the planet was colonised, their leader, Akha Vorass, went into the wilderness. He went mad from a combination of radiation and certain chemicals. He believed that Tarron spoke to him. He started the Vorassan cult and began killing and converting the colonists.
At this time, the Kephra came to the planet and saw the problems they were facing. They stopped the Vorassan cult and made the inhabitants immune to the radiation. Seeing they had no government left, they founded the Azmec Corporation to take control. To cement their rule, they faked a holovid about them being given control of the planet by Hal Simvoa. They also produced artefacts to add to their mystique: the Volumes of Garda and the Jewelled Headdress of Princess Maxtra.
Centuries later, the Kephra saw the Tarronians could develop the technology necessary for a Holoprobe. With this technology, they would see that the holovid was a fake. To prevent this, they kidnapped Akha Vorass from the past with a Time Scoop to kill the top scientists in the field. They also developed Holoprobes of their own and denied all requests to reconstruct the old holovids. The First Doctor and Dodo investigated and found the faked holovids. The Kephra were banished from Tarron and the Tarronian civilisation suffered from anarchy. (PROSE: Tarnished Image)
