Coralle

Coralle is the capital of the Shark Kingdom. The vast majority of its surface is covered by tropical oceans, and likewise the vast majority of its population dwells underwater. Under its surface, the royal family of the Shark Kingdom has lived in the Sunny Reefs Palace for time untold, and huge cities grown from genetically modified and magically enhanced coral glow brightly. The planet is infamous for catering to its underwater population almost exclusively, while land-dwelling citizens are left behind in poor coastal slums.
