History
Thunderbird Bay has long been an important cultural and economic crossroads between Yeongju and Sinju, facilitating contact and trade which greatly influenced the development of both regions. Several major civilizations developed on its coast, including the ancient Hachuabshi civilization. The bay also prominently served as the center of the widespread maritime raids of the Pekkou during the middle ages.

During the Age of Sail, the bay became an important hub of mercantile activity. Most trade between Sinju and Yeongju passed through the bay. This period saw the development of a regional pidgin language and known as the, or Wawa.

The bay remained an important area into the modern era, when it became an important front for naval power projection. The Great Eulhae War saw an intense struggle for naval supremacy over the bay. Following the war, the Thunderbird Bay Union was formed to facilitate trade and diplomacy between member states bordering the bay.
