Set Sail on the Dangerous Azurite Sea Disney Lorcana TCG: Azurite Sea continues the story of Illumineers who were last seen celebrating the defeat of Ursula in Disney Lorcana TCG: Shimmering Skies until they were interrupted by chunks of the Great Illuminary, the repository of all stories ever told, falling off and plummeting to the ground
