The bridge crystal, which is also known as the rainbow crystal, was a mystical artifact that belonged to the Ewok species. It allowed a person to create a Rainbow Bridge across the Gorge of Fire by standing at the gorge's edge and allowing the light from the suns to pass through it. This bridge served as the sole means of traversing between the forests inhabited by the Ewoks and the territory of Zandor; however, the rainbow would vanish if the sun's rays were interrupted. Chirpa, the Chief of Bright Tree Village, had taken the crystal from the Ogre named Gantu when he was younger, with the intention of stopping Gantu from attacking Ewok lands. Later, the crystal was unintentionally shattered during a conflict involving Gantu and the Ewok Teebo.
