Alien organisms known as extremophiles can become trapped in beautiful star crystals that are ejected into space after collisions between planets that harbor life. A star crystal can fetch a hefty price on the black market. The most sought after crystal is the very rare rainbow crystal whose mysterious energy glows with every color of the rainbow believed to be a shard of crystal from the initial formation of the universe.
The Naroony are the robot species commissioned by the S.P.A “Space Protection Agency” to protect the star crystals from intergalactic poaching by the feared cyborg alien race of star crystal hunters the Groks.
