Sun crystal

Sun crystals were precious stones mined on Jazbina that were famous for exponentially reflecting and brightening light. Miners were forced to wear heavy duty protective eyewear when dealing with the crystals as prolonged exposure to them led to light addiction and, ultimately, blindness. The mining tunnels were often home to large Tikulini worms.

Luke Skywalker was nearly blinded by sun crystals on Jazbina while supposedly rescuing Princess Syayna.
