Gathering Hall is a room in the Chozo Ruins in Metroid Prime. It is a large room with its ceiling open to the sky, and one side's floor is covered in toxic water until the defeat of Flaahgra. On this side, a number of small ledges allow access up to a Morph Ball tunnel, which leads around to a high up door.
