The Spirit Oasis is a verdant and lush garden located in a cave in the Northern Water Tribe's capital city at the North Pole. Although the land outside is perpetually frozen, the Spirit Oasis itself is warm. This is where the mortal incarnations of the Moon Spirit and Ocean Spirit live. The water of the oasis is said to contain unique healing properties. It is a place where the Spirit World overlaps with the mortal world. It is known to be one of the most peaceful places in the bending world.
