Castor is one of the twin stars that give the constellation Gemini (which means "twins" in Latin) its name. The other twin is Pollux, also part of the Outerworld Heavenly Bodies collection. In Greek mythology, Castor and Pollux were the twin sons of Zeus. They have a cameo appearance in the epic tale of Jason and the Argonauts. It is a little-known fact that Jason loved a good bowl of custard, and the Argonauts were particularly fond of apple pie.

Note: For a truly amazing vaping experience, reunite the twin sons of Zeus by mixing one part Castor with one part Pollux in the same tank / RDA. Be warned, it's highly addictive.
