The Alpheridians, a sentient species, originated on the planet of Alpheridies, which was located in the Expansion Region. This species shared their homeworld with the Miraluka, who undertook a mass migration to Alpheridies several millennia prior to the Great Sith War due to instability affecting their original home planet's geophysical and geo-chemical makeup. By the time of the Great Sith War, specifically 4000 BBY, Alpheridians comprised only 7% of Alpheridies' population, while Miraluka accounted for 90%. Some Alpheridian bounty hunters were seen on Tatooine around 0 BBY. The Rodian bounty hunter Greedo observed some of them entering Chalmun's Cantina within Mos Eisley.
Tom and Martha Veitch conceived the Alpheridians for their short story, A Hunter's Fate: Greedo's Tale. This story was included in the anthology Tales from the Mos Eisley Cantina, which was published by Bantam Spectra in 1995.
