Ra'ra'vis
The Ra'ra'vis were the avian natives of the planet Helion.
The Ra'ra'vis kidnapped Rassilon during the war with the Vampires. The Ra'ra'vis were defeated by Jorus and the Vogans, who subsequently freed Rassilon. (PROSE: Jorus and the Voganauts)
The Time Lords would later become known as legends to the Ra'ra'vis. (COMIC: Time Fraud)
Once each generation, the crystalline moons of Helion aligned with its sun at the Solstice of Pajaro. This created a beam of temporal energy (similar to a time corridor) that lasted for a few hours. Normally, the Ra'ra'vis used to this rejuvenate their old and sick. On one occasion, however. they used a rare double occurrence of the solstice in a time experiment, sending their first "chrononaut" to Earth many centuries earlier. He was saved by the Eleventh Doctor. (COMIC: Time Fraud)
A pair of Ra'ra'vis recruited the Fourth Doctor and Romana to retrieve a psychic sales voucher worth 13 million Grotzits in 1985 New York City. (COMIC: Time Lady of Means)
