The Misty Palisades (formerly known as the Blazing Palisades) is an island that appears in the Disney Junior animated series Sofia the First. The island has a rugged, rocky terrain, with winding paths, volcanoes (and geysers later on), and a mountainous top in the shape of a dragon.
The Misty Palisades is the island home of both the Dragons and Sea Monsters of Enchancia. Originally the the Blazing Palisades, it was an island covered in fire and home exclusively to Dragons, to whom it was a fiery paradise. The islands undying flames were fueled by an artifact known as the Eternal Torch, which was kept on a pedestal in a cave at at the top of the islands highest mountain.
The Palisades reaches its present state in "The Secret Library: Tale of the Eternal Torch". The Sea Serpents of Enchancia, who have always wanted to claim the Palisades as their home, arrive on the island with an artifact known as the Forever Fountain, a conch shell that unleash an endless torrent of water, dousing all the flames and flooding the island.
Sofia shows up to help the Dragons stop them, but Prince James, whom Sofia unintentionally brought along, ends up wrecking their plans in a way that enables the Sea Monsters to succeed in ascending the Palisades and putting the Forever Fountain on the Eternal Torch's pedestal, turning the Blazing Palisades into the Watery Palisades.
Sofia and James, with the help of the Dragons, manage to lure the Sea Monster away from the Forever Fountain and put the Eternal Torch back on its pedestal, but without removing the Forever Fountain first. This arrangement merges the magic of the two items, causing the lower half of the island to be covered in water and the upper half to be covered in fire. As well as the combination of fire and water creating a dazzling rainbow in the sky above the Palisades.
Seeing this, Aqualina, the leader of the Sea Monsters, declares a truce with Everburn, and from then on, the Blazing Palisades were known as the Misty Palisades, where the Dragons and Sea Monsters lived together in harmony and friendship,
