Bay of a Thousand Scales

The Bay of a Thousand Scales is a spiral of islands that make up the "tail" of the dragon-shaped continent of Pyrrhia, and could be considered to be an archipelago. It is said to have hundreds of islands, making it easy to hide the Summer Palace among them. It is the only landmass in the Sea Kingdom, and therefore it is ruled by Coral. The bay is also home to the ruins of the Summer Palace, which were enchanted centuries ago by Albatross, an animus SeaWing, to grow on its own from a rock. In addition, it is home to the Deep Palace and the location of the Island Palace. The SeaWings are currently working on a new palace that is not hidden and will be used for diplomacy and Queen Coral's scroll readings.

Description
These islands can range from huge islands with forests and cliffs to rock outcroppings that can only fit two dragons at once. Many of the islands are not listed on the map, as hundreds cannot be charted. Tsunami compared the islands' vastness to the size of the map, saying that the map's entire bay fit in her talons.

The SeaWing palaces are located in the Bay of a Thousand Scales, and they are also the home to some more private dragons that live by themselves.

Outer Isles
The Outer Isles are a part of the Bay of a Thousand Scales mentioned by Fin.

The Lost Heir
The Bay of a Thousand Scales was both the place where Riptide first met the dragonets of destiny and the location of Blister's hideout. The Summer Palace was hidden on one of the islands, along with the SeaWings' above-water prisons, and is the book's main setting. Kestrel, after being murdered by Blister and Morrowseer, was also found on an island close to the Summer Palace. It was firebombed in a SkyWing attack, and is currently in ruins.
