Abraxas is a sci-fi-sounding name with earthly possibilities, but some playground challenges. 
 Abraxas has a long and convoluted history, dating back to ancient Egyptian mythology and the Gnostics who worshiped him as the Supreme Being. The name Abraxas was carved on antique gemstones that were used as charms.
 Abraxas lives on in modern pop culture, as the name of the musical group Santana's second album, in Harry Potter and the Half-Blood Prince as Draco's grandfather, on several TV series and video games, and as a cosmic entity in Marvel Comics.
 Trivia note: Abracadabra was based on Abraxas.
