Phasma was born in 6 ABY and died in 34 ABY.
Phasma, a stormtrooper captain of the First Order, grew up as a member of the Scyre clan on the nuclear-ravaged world of Parnassos, where she became a formidable warrior, eventually becoming the clan's military leader. Seeking passage offworld, Phasma helped the First Order General Brendol Hux find his ship, in the process betraying her own brother, Keldo, and the rest of her clan. After being rescued, Phasma joined the First Order, abandoning her former life.
