In order to gain access to the Hall of Radiance, the player must first enter Lower Ice Cave 3 from the main area of the Weddell Sea. After doing so, they will pass through the Crystal Globe, an area named for its beautiful ice structures resembling gemstones, and then go through a twisting tunnel, emerging in the Hall. The first time the player has to go into the Crystal Globe, the way into the Hall will be blocked by large spikes of ice, which the player must break with the help of the Leopard Seal that lives in the dome (the sound of the Sea Whistle causes the seal to charge at the player, and when the player dodges the Leopard Seal rams into the ice blocking the way instead, breaking it).
