Lanayru Province is the third province accessed in Twilight Princess. It is also the largest province in the game. The Lanayru Province is located west of the Eldin Province and east of the Peak Province (in the GCN version). Hyrule Castle, Castle Town, Lake Hylia, and Zora's Domain are all located here.
The Lanayru Province is one of the three major regions of Skyward Sword. It is a large desert-themed area, but it was not always that way. Lanayru Desert was originally filled with lush scenery and was able to grow Ancient Flowers. Link views this past glory upon striking Timeshift Stones permeating the region. That was until the war between the Goddess and Demon King ensued. Afterward, the province was nothing but never-ending seas of sand and rolling Tumbleweed. The Ancient Robots could no longer thrive in such conditions.
