Crystals of Rafa life were a kind of yellow colored crystal. The crime lord of Crimson Dawn, Dryden Vos, possessed no fewer than six of these crystals located within his personal museum on the First Light during 10 BBY. The name was the same as the Rafa system.
The 2018 film Solo: A Star Wars Story, an anthology film, marked the initial appearance of Rafa life crystals. Their identification was later confirmed in Solo: A Star Wars Story The Official Guide by Pablo Hidalgo.
