The Deep Palace is the underwater home of the SeaWing royal family, hidden deep within the Kingdom of the Sea. Built around the Royal Hatchery, it is a vast coral structure filled with glowing reefs, winding tunnels, and gemstone-studded halls, making it even more magnificent than the former Summer Palace.

Queen Coral resides here year-round, ruling from within its guarded depths. The palace once held an enchanted statue of Orca, which secretly destroyed female royal heirs until it was discovered and destroyed. After the Summer Palace was ruined in war, the Deep Palace became the primary home for all SeaWings.

Inside, the palace contains notable features like the Royal Hatchery, kept warm by bubbling currents, and the Bubble Jet Garden, where young dragonets play. Though beautiful, the Deep Palace also reflects the strict and sometimes ruthless rule of the SeaWing monarchy.
