History:
Tephrike has always been a peripheral planet of minuscule importance. However, its fate has been closely linked to the ebbs and flows of galactic politics. After the Battle of Ruusan, the Galactic Republic enjoyed an age of peace. Enacting the Ruusan Reformation, the Galactic Senate demilitarised the Republic. Likewise, the Jedi renounced their military ranks, disbanded the Army of Light, believing that the threat of the Sith had been banished with the destruction of the Brotherhood of Darkness. This makes it a tremendous irony that one day a Jedi theocracy would come into being upon this insignificant planet. Of course, it is extremely unlikely that Lord Hoth would have approved of the regime on Tephrike.
Regardless, the planet was discovered in 500 BBY. Initially, pirates used it as a base that was out of the way and beyond the reach of law enforcement organs. However, they found the native wild life to be extremely dangerous. Much later, legitimate private enterprise came across the planet. The corsairs were driven out and capitalists from the Core Worlds were attracted by the ample supply of timber and exotic animals.
It helped that Tephrike was not inhabited by indigenous sentient life. Natives always made colonisation awkward since they resented the terra nullius doctrine. Colonial wars were expensive and generally produced negative PR. However, as the private companies soon discovered, while Tephrike was beautiful, it was also home to manifold dangers. This slowed down colonisation to a large degree. To a large extent, the initial settler population was drawn from convicted felons, who were given a second chance by performing menial labour on the jungle world. This was a convenient way to free up prison space.
Occasionally, convicts escaped into the wilderness. Those who survived the experience became raiders, which also gave the corporate settlements another reason to stock up on defences. However, Tephrike also attracted aquatic aliens such as Nautolans and Quarren. Some of them were political activists disgruntled with conditions on their homeworlds for this or that reason. Tephrike's oceans and seas were a natural fit for them. However, these alien colonists refused to follow the rules of the corporations that had been turning Tephrike into a corporate state. Moreover, many of the original colonists were humans or near-human. As a result, conflict over settlement rights were inflamed by racial tensions.
At the same time, environmentalists complained about the effect colonisation was having on the environment. In one case, radical animal rights activists tried to free captured animals, causing a number of deaths. As a consequence of these incidents, the Republic Senate got involved. The Jedi Order dispatched Jedi Knights to mediate, producing a compromise settlement that, in the spirit of compromises, satisfied no one but left the involved parties better off than in the past. The order set up a Jedi enclave, not only to keep the peace, but also to ensure that Force-sensitives born amongst the settler population received proper training after a darkside cult led by a radical Quarren tried to foment civil war on the planet. Following the end of the Naboo Crisis, a community of Gungan exiles who rebelled against the strict laws that held sway in Otoh Gunga established a colony.
The Jedi's presence would turn out to have long-lasting consequences for the people of Tephrike, for it made the planet a target after the Republic was transformed into the Galactic Empire. Jedi had, after all, been declared enemies of the state following Mace Windu's failed coup d'état. Aside from skirmishes with Separatist forces, Tephrike had largely escaped the Clone Wars unscathed.
This changed when Imperial forces descended upon the planet. The Jedi enclave was razed, and the new Imperial governor inaugurated a humanocentric colonial regime. A few Jedi survived the Purge and escaped into the jungle or aquatic regions, where they continued to resist the Empire by using guerrilla tactics. However, even with the help of persecuted aquatic aliens, their ability to bring about change was limited. To combat the partisans, the Imperial forces employed brutal scorched earth tactics, including the use of herbicides, napalm and chemical weapons. However, the colonial government also united Tephrike's scattered settlements and built the planet's first capital, Palmyra. Following the Battle of Endor, the colonial government lost contact with Coruscant, as the Empire began to self-destruct.
With no one further up in the hierarchy to oppose him, the Imperial governor became a warlord. An exorbitant fortune was spent on grandiose construction projects, such as hydroelectric dams and a new palace. These were financed by nationalising private assets and forcibly extracting tribute and population, which also had to provide forced labourers. However, the regime's harsh policies and notorious corruption produced resistance. Already weakened by internal power struggles, the regime was overthrown by a popular revolution with the aid of the fledgling New Republic. In its place, the native set up a federal republic loosely based on the Old Republic. Protection of racial minorities was enshrined in the constitution, which also specified that a minimum number of seats in the parliament should be reserved for minorities. This was a well-intentioned response to the humanocentrism of the Imperial regime and the racial strife that had plagued Tephrike in the past, but would turn out to be an error.
