Peladonian The Peladonians ( or Pels ) were a race of humanoid s native to the planet Peladon who retained a feudal culture . Physical characteristics . Peladonians were nearly identical to human s , with whom they could reproduce . One of the few ways to tell them apart was the burgundy streak through their white or blond hair . This streak would grow in during adolescence . The other difference was the life - span . Even with medical technology , the Peladonians rarely lived past 65 . Before the Galactic Federation ' s help , they would be lucky to live past 50 , and barely 40 for the miners . Some Peladonians had blue eyes , which was considered a trait for scholars . ( PROSE : " Legacy " ) Culture . The Peladonians had only one culture , presumably due to the actions of King Erak . All Peladonians were brought together by the worship of Aggedor and the commands of the King . ( PROSE : " Legacy " ) The Peladonians lived in a feudal society , which had two main classes . The upper class was ruled by a King , who had a High Priest and Chancellors . The upper class had fewer laws and more privileges . The lower class performed all the physical labour , such as the mining . There was also a distinction of rules between men and women . ( TV : " The Curse of Peladon " ) For example , only women of noble blood were allowed in the court - room ( TV : " The Curse of Peladon " ) and commoners could be killed for even asking . ( PROSE : " Legacy " ) Following their entrance to the Galactic Federation , they attempted to improve rights for their poeple , though there was opposition to this . ( TV : " The Monster of Peladon " , PROSE : " Legacy " ) The most important figure for the Peladonians was Aggedor . Though it was originally just a noble animal , it eventually came to be worshipped as a god . Aggedor was thought to curse the enemies of Peladon , and defiling the Temple of Aggedor was punishable by death . ( TV : " The Curse of Peladon " ) Though some Peladonians still worshipped Aggedor at that time , by the 41st century , Queen Elspera " did away with religion " , dissolving any churches of Aggedor worship , or as Princess Pandora of Earth and King Pelleas put it , Pandora wouldn ' t need to convert to " Aggedorianism " upon marrying Pelleas . In spite of her modernisation of Peladonian culture , however , during her reign , Elspera did not ban arranged marriage . ( AUDIO : " The Bride of Peladon " ) Most Peladonians kept their hair long and slicked back to show off their stripe . Miners , on the other hand , kept their hair short and curly and brushed it so that it would cover their ears and protect them from grit . They would also dye it black with white flecks . Several sacred artefacts of the Peladonians were the Sword of Truth , the Crown of Sherak , the Chalice of Blood and the Lance of Aggedor . Alcohol was illegal on the planet . ( PROSE : " Legacy " ) History . Early history . Early in Peladon ' s history , the Peladonians were divided into tribes which would select a headmember to serve on a council . This all changed when King Erak attempted to take over the whole planet . He was a cruel king who killed anyone who disobeyed him and forced his people to build him a citadel on Mount Megeshra . He was eventually overthrown by Gart and his son Sherak , though Gart allowed Sherak to take the credit and become king . Five years later , Sherak planned to explore the dark side of Mount Megeshra . His father thought this idea was suicide , and when Sherak refused to listen , he left forever . Sherak went ahead anyway , but accidentally fell down a cliff . He encountered an Aggedor , and when it saved him from four other Aggedors , he named the Aggedor protector of the royal family . ( PROSE : " Legacy " ) Dealings with the Federation . Many generations later , King Kellian had come into power . In 3864 , Princess Ellua of Earth crashed on Peladon after one of her ships was damaged in an ion storm and the other ships tried to save it . After helping her contact the Galactic Federation , the king fell in love with her and they married . Six months later , Peladon applied to join the Galactic Federation . They decided that Peladon needed more time to develop , and planned to return in 3885 . In 3865 , Ellua had a son named Peladon . In 3877 , Kellian was killed in a hunting accident and Peladon came into power . Circa 3885 , Peladon was trying to get Peladon accepted into the Galactic Federation , a move opposed by more conservative Peladonians , such as High Priest Hepesh . In the original timeline , Arcturus would have killed Alpha Centauri and blamed the Ice Warrior s . This would lead to infighting in the Federation , allowing the Dalek s to take over the galaxy unopposed . The Time Lord s sent the Third Doctor and Jo Grant to Peladon to avert this , and Peladon was accepted into the Federation . ( TV : " The Curse of Peladon " , PROSE : " Legacy " ) Circa 3935 , during the Federation ' s war with Galaxy 5 , the planet was found to contain trisilicate , which was vital for the war effort . The lower class was forced into mining the trisilicate , which caused further unrest between the classes . ( TV : " The Monster of Peladon " ) In 3985 , King Tarrol , the son of Thalira , invited Federation delegates to Peladon for his coronation . During the course of this event , many of the sacred artefacts were stolen , the Seventh Doctor was accused of the murder of Lianna and " executed " , all alien s were banished from Peladon , the Ice Warrior delegate Savaar was blamed and " executed " for attacking the High Priestess Atissa , and the Diadem , an ancient artefact of evil , was brought to Peladon . In the end , the problems were solved , but the Advisor Geban was killed by the criminal Nic Reece and the High Priestess Atissa departed for the dark side of Mount Megeshra . Seeing the destruction that had been done , King Tarrol decided that Peladon needed to see if it could survive on its own , and severed all ties with the Galactic Federation . Though King Tarrol intended the Federation to return in 4035 to see if more help was needed , the Dalek invasion in the 4010s meant the collapse of the Federation . ( PROSE : " Legacy " )
