Kami-shima is an island in The Shield area of the Wushanko Isles. It is unlocked after the final trio voyage between the Tengu, the Exile, and the Memory, and was the location where Davosi had been creating a second Scarecrow to use against the world guardian.
The island was kept secret and well-hidden by the Ten Gu due to its extremely high levels of magic and anima, which causes it to be the source of the various sea monsters, which are also created from anima. It also acts as the centre force of an energy barrier similar to the Edicts of Guthix which protects the Eastern Lands from the influence of the gods.
During the Guardians of the World missions, the island is described to "come alive" and created shi-guardian lions, known from Gu folklore, to assist the trio in defeating Davosi and his employees, who wished to drain its energy to power the new Scarecrow.
