The Great Plateau is a location from The Legend of Zelda: Breath of the Wild. It is one of the main regions of Hyrule and the first region discovered and visited by Link after his awakening from the Shrine of Resurrection. According to the Old Man, it is the birthplace of the entire kingdom of Hyrule. The Great Plateau is a secluded piece of land separated from the rest of Hyrule by its massive height and large walls. The plateau is the only place void of Guardians, although there are decayed Guardians near an area of the plateau that will reactivate and attack if Link tries to approach. The Great Plateau Tower is buried deep underground, surrounded by rubble and debris. When activated, it will rise high above the ground and trigger the rise of all the other Sheikah Towers throughout Hyrule. After the tower's activation, Link completes his first four shrines and obtains his first four runes for the Sheikah Slate.
The Great Plateau region itself is located near the center of Hyrule, southwest of Hyrule Field and northwest of Lake Hylia regions. The Shrine of Resurrection is located there. The ruins of the Temple of Time are located within this region southeast of the Forest of Spirits, and the Eastern Abbey east of the Temple of Time. The Temple of Time contains a Goddess Statue, which Link can pray to. According to the Old Man, the place was the site of many sacred ceremonies before the Great Calamity. The Woodcutter's House is found south of the Temple of Time; this is where the Old Man lives. Owa Daim Shrine is found atop the cliffs near this area. In addition to Woodcutter's House, the Old Man has created several camps, one near the Shrine of Resurrection and another in the Forest of Spirits. Mount Hylia is located in the southwest portion of the plateau near the River of the Dead, and the Keh Namut Shrine lies at its northern edge. While most areas of the Great Plateau are temperate, Mount Hylia and the River of the Dead zones are cold and snowy.
The Eastern Abbey contains the Ja Baij Shrine surrounded by several decayed Guardians who will attack if approached. North of the Eastern Abbey is a steppe-like region where the Great Plateau Tower lies dormant until its awakening. Still further north is where the Oman Au Shrine may be found. Like most regions of Hyrule, several Koroks can be discovered all over the Plateau to be rewarded with Korok Seeds. As it is isolated from the rest of Hyrule, there are no horses to be found and Link is unable to summon Epona using the amiibo Rune within the Plateau itself. However, the amiibo rune can be used to summon Wolf Link.
The Plateau contains minor enemies such as ChuChus and Bokoblins. Keese and Stalkoblin also appear on the Plateau at night. White ChuChus inhabit the cold areas of Plateau. A Stone Talus can be found in a small clearing in the Forest of Spirits. As Link progresses through the game, Black and Silver Bokoblins will start to appear on the Great Plateau, making travel through the region slightly more dangerous.
After awakening in the Shrine of Resurrection, acquiring the Sheikah Slate, and encountering the Old Man, Link is guided to the Great Plateau Tower and must activate it. The Old Man directs Link to find the four Shrines of the Great Plateau and return him back their treasures, the Spirit Orbs. He then reveals himself to be the spirit of King Rhoam Bosphoramus Hyrule and tells more about the past events. After requesting Link to seek out the Sheikah Impa at Kakariko Village, he offers the paraglider allowing Link to leave the plateau.
The Old Man says that the Great Plateau is the birthplace of Hyrule. One possible conclusion to draw from this statement is that the Plateau may be in fact be Skyloft from The Legend of Zelda: Skyward Sword. However, the lack of landmarks resembling those from Skyloft means the Old Man may have meant something entirely different.
