Ice Castle is a Second Sea island known for its massive frozen fortress and distinctive icy terrain. It stands out as one of the more visually striking locations in the Second Sea due to its large scale and cold atmosphere.

The island is dominated by a huge central castle that towers over the surrounding area, making it the island’s most recognizable landmark. Around the island, players can see large flat chunks of ice floating both in the water and near the shoreline, reinforcing its frozen theme.

Ice Castle is located north of Dark Arena in the Second Sea, making it easy to identify when traveling through the northern part of the map.

Additional Information:

• Using the Library Key to unlock Phoeyu, The Reformed permanently unlocks the door, allowing the player to return anytime, even after leaving the game.

• The Hidden Key and Library Key do not save in the player’s inventory after leaving the game.

• The Hidden Key can be used beneath the stairs where Awakened Ice Admiral spawns to open a hidden chest and obtain Rengoku.

• Ice Castle is often visited by high-level players farming for the Hidden Key, so grinding there can be risky.
