Geography
A path to the northeast of Ula'ula Meadow will lead to the entrance. There will be a stone bridge on the lake straight ahead with two decorative towers on the sides that have what appear to be compass roses in the middle. The bridge leads to a massive shrine where the player enters. It leads to a room with crumbling walls and sunlight seeping through and a stairwell downward. The player enters to a long hall with water running down the walls and many doors, some being blocked by piles of rubble. At the end of the hall are two small stairways that lead to the outside where there is a bit of greenery, such as trees, bushes, and grass, and a path down the middle to lead to a stairwell with more compass rose towers. Up the stairs is another but smaller stairway with pedestals with the Sunne symbol on them on either side. Up those stairs is a large, circular platform with a tiny bit of stairs leading to a spot in the middle. On it will be a darker gray rhombus with a blueish-gray Sunne symbol in the middle. All of the outdoor areas are foggy.
