As we continued our quest, we learned that the last two crystals were not just any elements - they were the forces of light and darkness themselves.
The crystal of light was said to be held in a temple of the gods, while the crystal of darkness was said to be held in the underworld.
We knew that these would be the most difficult crystals to obtain, but we also knew that we had to try. We journeyed to the temple of the gods, where we faced trials that tested our worthiness to even be in the presence of the crystal of light.
After passing the trials, we finally obtained the crystal of light. But the journey wasn't over yet - we still had to travel to the underworld to obtain the crystal of darkness.
