They eventually came into conflict with the Earth Alliance , who fought and defeated them around 3562 . ( AUDIO : " The Sirens of Time " ) After their defeat , the Knights were isolated on their planet , where they slowly recovered . In 4162 , First Knight Praylaron sensed the coming threat of the Dalek s , and surreptitiously worked to negotiate a new alliance with the Earth Alliance , sending Kalendorf to Vega VI as an envoy . Unfortunately , the invasion of the Daleks from the neighbouring Seriphia Galaxy halted the proceedings before arrangements could be made . After the Daleks had established their own Dalek Empire , Kalendorf worked with Susan Mendes and Daleks of a parallel universe to defeat the Daleks of their own universe .

Twenty - five hundred years later , archaeologist Saloran Haredew investigated a series of " psychic recordings " made by Kalendorf on Velyshaa . She handed off the information to Siy Tarkov , who used the information to warn the Galactic Union about another Dalek Invasion . ( AUDIO : " Dalek Empire III " ) Alternate timeline . In an alternate timeline created by the Sirens of Time , the Knights were not defeated in 3562 due to the Earth Alliance never developing . They rescued Sancroff from exile and proceeded to build the Second Velyshaan Empire . They captured the Temperon and used the temperon particles it generated to gain time travel . However , prolonged exposure to temperon particles caused the Knights ' bodies to slowly waste away . They conquered whole galaxies and extracted their life forces to sustain their decaying bodies . Their greatest triumph was the conquest of Gallifrey and the subjugation of all Time Lord s to their life force extractors . This timeline was destroyed when the Temperon locked the Sirens of Time in eternal combat , undoing the nexus points that allowed the rise of the Second Empire . ( AUDIO : " The Sirens of Time " ) Skills . Knights of Velyshaa were skilled in " all the ancient arts . Telepathy , espionage , mortal combat . . . " ( AUDIO : " Invasion of the Daleks " ) Most notable of their skills was the ability to telepathically connect with others through touch , allowing private communication and channelling of psychic energy .

Kalendorf told a legend that all of Sancroff ' s lieutenants took a vow of " Victory or Death " and remained fiercely loyal to him , except for one lieutenant named Satiricius , who plotted to overthrow him . When Sancroff learned of her impending betrayal , he met with her in private . Immediately after that meeting , Satiricius returned to her castle and killed all of her fellow conspirators , then herself . It was rumoured that this was a psychic compulsion impressed on Satiricius by Sancroff during her vow . ( AUDIO : " " )
