Trial of Light and Shadow

The group arrives on an island floating above the clouds. Yugi faints from the strain the armor put on the Pharaoh. A new message arrives and Grandpa deciphers it. "The Trial of Light and Shadows: Once a day, the unbrekable stone appears in the Valley of Light. To break fight with a force greater than physical might." Deciding to give Yugi a break from saving them, Joey, Tristen and Grandpa head out to complete the challenge alone. They find the stone, but soon have to fight Prisman to break it; Tristen sees the energy blasts the monster lets out damage the rock, so he irritates Prisman to get it to start cracking it. Yugi awakens, and Tea gives him the message; switching to the Pharaoh, they discover it has a second message when read in the dark. Prisman is successfully destroyed once it breaks the rock, but Skull Guardian takes its place. The Pharaoh merges with Dark Magicion once more, only subdoing the monster; the second half of the message said they needed to only defeat the monster, not kill it, thus proving themselves peaceful. The masked man arrives and reveals that if they fail the five trials, they will be stuck there until another challenger arrives; if the Pharaoh succeeds, he will be given the power he's worthy of.
