Ordona Province

From Zelda Wiki.org

Ordona Province is part of the province system of Twilight Princess. It is located at the southern end of the map and is by far the smallest province in the game. It includes Ordon Village, Link's home village, Ordon Ranch, and Ordon Woods. It is connected to Faron Province to the north. It is watched over by the Spirit of Light Ordona.

Ordona is not considered part of Hyrule by some, such as Shad, but it is never specifically made clear if Ordona is part of Hyrule or not.

It seems that the Ordona Province exports food to the other provinces. The only things that the people from Ordona could export are Ordon Goat Cheese and Ordon Pumpkins. Curiously, when Link is trying to find the Big Key in the Snowpeak Ruins, he first finds Ordon Goat Cheese and an Ordon Pumpkin, because Yeta, the female Yeti who lives in the Snowpeak Ruins, is sick and couldn't remember where the Bedroom Key was. How the food from Ordona came there is not revealed. The Cheese and Pumpkin are put in the soup Yeto is making and every time you add an ingredient, the soup heals more health when you put it in your bottle and drink it.

Also, near the beginning of the game Link is asked to deliver a sword to Hyrule, but it seems that this does not happen regularly.
