Iwanai Island

Iwanai Island is the island in the southwest corner of the worldmap. It is accessible only by completing the quests Deep Sea Demo #1 and #2, and therefore learning Dive (see Walter for more information). It includes the city of Iwanai Town, the sacred Uked Tree, and the Antarak Volcano.

Iwanai Town
This is a very primitive city in the middle of the island, home to islanders who insist on calling you "visitor". This is where you can complete the following Quests:
 * Daddy Search (little girl in the top right of the map)
 * Fruit Search (father of the little girl, in the same place, after completing "Daddy Search")
 * Stone of Sun (20,000 TP required, talk to the Elder in the top-right hut, grants access to Shattered Red and Blue, which allows you to battle Groudon and Kyogre)

Uked Tree
This is an area of the island that is hidden.
