Eastern Sea

The Eastern Sea is a large body of water located in the eastern Earth Kingdom. It lies roughly midway between Ba Sing Se and the Eastern Air Temple. A small waterway connects this sea to the East Lake.

History
For much of history, the Eastern Sea has been administered by the Earth Kingdom, but has fallen under foreign control multiple times due to it's strategic location. Chin's army captured the shores of the sea during the War of Chin the Conqueror, but were liberated shortly after his death at the hands of Avatar Kyoshi.

The Eastern Sea remained at peace until the Hundred Year War commenced centuries later. Ships from the Fire Nation continually invaded the area, attempting to break through it's defenses and reach Ba Sing Se. In 97 ASC, the forty-first division of the Fire Nation military arrived at the Eastern Sea. A general in the Fire Nation suggested that they leave the sea and head north to fight a powerful battalion of earthbenders near Ba Sing Se. He was met with criticism because the forty-first division consisted of new recruits that could not fight well. The general retaliated by saying that the division could be used as a diversion from another attack, but Prince Zuko argued that this idea was immoral and would lead to the death of many soldiers that respected the Fire Nation. He was subsequently punished by his father for speaking out of turn.

Later that year, Hakoda and his troops from the Southern Water Tribe completed their journey to the Eastern Sea, where they began to help defend Ba Sing Se from attacks. Here, Hakoda invented the tangle mine, a weapon used to combat invader ships. One night years later, while on a cutter ship in the middle of the sea, he spotted a lost Appa flying high above him.

Hakoda reunited with his son, Sokka, during the spring of 100 ASC. At the time, his troops' base camp was stationed on the northern shores of the sea, at a beach. Shortly after their reunion, the two went off to fight a group of ships entering the sea. However, the battle was interrupted by Aang, who informed Sokka of his vision that Katara was in trouble. He left with him, leaving behind his father after a very brief reunion.

Shortly thereafter, Hakoda left the Eastern Sea to fight in an invasion of the Fire Nation. He brought his warriors with him.
