Seaport village

The seaport village is a small coastal settlement in the western Earth Kingdom. An important port on the Mo Ce Sea, the village was captured by the Fire Nation during the Hundred Year War. They brought coal from the inland to this village, where their warships could be refueled and again put into use. One of the village's major landmarks is a large prison rig located several miles offshore.

History
Team Avatar briefly visited the seaport village during the autumn of 99 ASC. After Katara was arrested for what Fire Nation guards believed to have been earthbending, she was brought by cartwheel to a ship in this village. Her friends, secretly disguised as village natives, watched her safely board the ship. She was then taken to an offshore prison rig, where earthbenders were held captive until further notice. Made of metal, the benders had no chance of escaping the rig, a fact that quickly drained the hope of those that were imprisoned.

Here, Katara reunited with Haru and met his father, Tyro. She was disappointed to see how depressed the prisoners were, including Tyro. Katara attempted to motivate them with an inspirational speech, but to no avail. Afterwards, Aang and Sokka snuck into the prison and told Katara to find Haru so they could leave, but she refused. Instead, she persuaded them to help generate a prison break so she could save everybody. Sokka devised a plan that would bring coal to the earthbenders, allowing them to fight back against the warden's authority. Aang successfully executed it, and, with one final verbal push from Katara, the prisoners began resisting the firebenders. After defeating all the guards and throwing the warden overboard, the earthbenders blew a hole in the prison wall and escaped. Their dreams were to re-conquer their homelands from Fire Nation rule and bring peace back to the Earth Kingdom. In the midst of the battle, Katara soon realized she had lost her mother's necklace, although it was later recovered by Zuko.

Layout and description
The seaport village is surrounded by tall, barren mountains on three sides and the Mo Ce Sea on the other. The village's harbor is U-shaped and has three wooden piers that jut into it. Only one of the piers can dock large ships; the other two to it's right are far smaller, so only small ships can dock there. A thin strip of beach sand separates the village from the harbor. Some sailors and natives leave their boats here instead of the piers as they enter the village. A boardwalk on the beach connects to one of the piers, allowing room for easier access to it.

The village is divided into two halves by a wide, straight avenue. On either side of the avenue are low-rise buildings made of wood. They have green rooves that are bordered by thin yellow outlines. The rooves are triangular and have no shingles. Some of the buildings are houses, while the others are markets. The village's marketplaces are quite lively and bustling with commerce.

Fire Nation prison rig
The Fire Nation prison rig is a towering facility that serves both as a dockyard for the Fire Nation Navy and as a prison for captured earthbenders. It is capable of holding hundreds of prisoners and is run by a cruel warden who delights in mocking his prisoners, who he refers to as his "guests". The facility processes coal for warships and is made entirely of metal, which no earthbender besides Toph can bend. This is the perfect environment to deprive the earthbenders of their bending and drain their desire to resist their captors.
