The Mo Ce Sea is an open body of water located between the western Earth Kingdom, eastern Fire Nation, and the United Republic of Nations. It is connected to West Lake, which is located southwest of Ba Sing Se.
The sea serves as a route for trading operations and is most notably the location of Crescent Island, once the site of the Fire Temple, and the seedy merchants pier, an important black market trading center. The Mo Ce Sea experienced countless naval battles during the Hundred Year War and played host to a massive Fire Navy blockade aimed at keeping all outsiders from Fire Nation waters. It also connects to Republic City through an inlet known as Yue Bay.
Years later, her successor, Avatar Kuruk, and his bending teachers traveled to the same island to learn how to control the Avatar State. The journey ended with him destroying the island and almost killing his friends.
In 295 BG, Kyoshi and Jinpa flew over the Mo Ce Sea on the latter's flying bison, Yingyong, on their journey from Ba Sing Se to the Fire Nation Capital to celebrate the Festival of Szeto. Kyoshi fell off the bison once she received a painful vision of Kuruk. She later returned to the ruined island while leaving the Fire Nation, where she crossed over to the Spirit World and truly met Kuruk for the first time.
Aang and his friends journeyed across the Mo Ce Sea in order to reach the Fire Temple before sunset on the winter solstice to see Avatar Roku. As they neared the Fire Nation border, they encountered a Fire Navy blockade under control by Zhao, a Commander at the time, who ordered his forces to attack the Avatar by catapulting fireballs at the incoming flying bison. Prince Zuko, also in hot pursuit of Aang, chose to cross the Mo Ce Sea into Fire Nation waters despite having been banished from the Fire Nation. Aang, Katara, and Sokka managed to evade the blockade and reach the temple in time for Aang to talk to Roku.
Seventy years later, in the immediate aftermath of the collapse of Amon's Anti-bending Revolution, he and his brother, former Councilman Tarrlok, traveled across the sea to escape from Republic City and start a new life. Here, Tarrlok blew up their speedboat, killing them both instantly.
In 171 AG, Korra crossed the Mo Ce Sea in attempt to reach the Fire Nation, but was soon attacked by her cousins, Desna and Eska. Though their attacks were initially successful, the twins retreated when they saw a dark spirit lurking in the sea, which Korra tried to purify by going into the Avatar State. Her attempt failed, however, and the twins watched as the spirit forced Korra below the surface of the water.
- After the Hundred Year War, a pro-bending team named the Mo Ce Mongoose Lizards was formed.
- "Mo Ce Sea" translates to "lonely, sorrowful sea" in Chinese.
