Almia Castle (Japanese: アルミアのおしろAlmia Castle) is a location in Pokémon Ranger: Shadows of Almia. It is only accessible through the Ice Lake to the south; the player must capture an Empoleon in order to cross the lake and gain access to the castle. The player first arrives at Almia castle after being ordered there to research the Tears of Princes. On this mission, the player must capture a Lucario that is guarding the Blue Gem.
The castle also has a place in Almia's mythology. As described in folktales, this was where the King of Almia lived, along with his son in blue, after his other two sons were banished to Volcano Cave and Hippowdon Temple. In the quest Mischievous Sneasel, the player captures a Sneasel that becomes a new Partner Pokémon. Once it is captured, it goes to Partner Farm and stays there unless the player chooses to take it with them.
Almia Castle is characterized by a large amount of ice and snow present both inside and outside. It is home to several Ice-type Pokémon, along with two Fire-type Pokémon (Vulpix and Ninetales) that provide the field move Burn to clear targets such as unlit torches and large chunks of ice. It is also one of the three locations of a Legendary titan, Regice.
