Hytopia Castle

is the seat of Hytopia's monarchical government in, presided by King Tuft and his daughter Princess Styla. The castle is located directly within the town of Hytopia. It notably contains three Triforce-shaped portals, the Triforce Gateways, as the only known entrances to the Drablands.

Features and Overview
Hytopia Castle has three designated lobbies inside used to enter the Drablands, with a Triforce Gateway in each one. These include the Multiplayer Lobby where multiple players can enter the Drablands using wireless connections, the Hall of the Doppels where a singular player can enter the land with two Doppels, and the Coliseum Lobby where the Links can participate in Coliseum battles taking place in the Drablands.

Each Lobby has a Master who will open the Triforce Gateway, and a small library containing diary entries where Mr. Tudor can be found. The Multiplayer Lobby and the Hall of the Doppels also each have a Drablands Challenge Completion List showing Link's Level progress, as well as Madame Couture's Assistant, who shows the Catalog and Material List. As only groups of three are permitted to enter the Drablands, these rooms take precautions to ensure that Link is paired with two more heroes before entering the land—either by matching him with other Links, or by awakening the Doppels to accompany him.

The Castle also has a throne room where Link is summoned to speak with King Tuft. He congratulates Link on clearing the Woodlands and encourages him to bring peace to his land by completing all challenges in the Drablands, including Drablands Challenges. Once Link has been summoned, he is free to visit the King anytime in his throne room. Link can speak with him after clearing all challenges of a particular Area to receive its exclusive, gold-ranked Material.
