The Gale reached the abnormal waters, where the crew prepared to use Hirwa’s Cloud-Clearing Ship to continue toward the island.

• Ace spotted a massive bridge and a Guardian statue that challenged the bearer of the Dawn Blade to a trial of wisdom.

The truth was broadcast in a pillar of light and scattered across the world as Aokiji and Star arrived too late to stop it.

• Raphael revealed the final Poneglyph, and Robin used the Knower’s Eye to decipher the Ancient Kingdom’s history and the meaning of the D clan.
