Hidden Village

The Hidden Village is a location from The Legend of Zelda: Twilight Princess. This barren, western-style town was once occupied by protectors of the Royal Family of Hyrule. Impaz, an old woman named after the the one who built the town, (probably Impa), lives there in solitude under Royal Decree. Since it was abandoned, the town has been overrun by a band of Bulblins, who constantly patrol the area, stopping Impaz from ever leaving her home.

Other than Impaz and the Bulblins, several cats inhabit the village. A Howling Stone and the Cucco Leader are also found in the village. During the Twili invasion, the only entrance into the town is blocked by a massive boulder. Darbus, leader of the Gorons, breaks through the rock to repay Link for saving him from his mutation caused by the Fused Shadows.

Ilia spent some time here with Impaz. She left the Horse Call with her, which was instrumental in restoring her memory.

Link's Crossbow Training
The Hidden Village appears as a location where the game takes place. Link must walk through the Hidden Village and shoots all 25 of the Bulblins before time runs out.

Super Smash Bros. Brawl
The musical track from this area, "The Hidden Village", appears as one of the available songs for the Bridge of Eldin stage.

Theory
Impaz states that she was named after the founder of this village, her name makes a strong resemblance to Impa. It could be concluded that this village is the original Kakariko Village as it resides in a similar location, and that could be was founded by a Sheikah, due the fact that Impa and Impaz are from this tribe. Such a theory gains strength when translating the Hylian Language in the Hidden Village, as two big billboard says "Welcome to Old Kakarico" (the "c" is a probable misspelling or some sort of Old Hylian language, which later evolved into the Hylian language as it is now known).

Additionally, in Link's Crossbow Training, the level of the Hidden Village is called 'Kakariko Shootout'.

Impa was noted to have been "born and raised" in the original Kakariko Village, so therefore the Kakariko of Ocarina of Time is not this town, as Impa was not the founder. Assuming this, there are three Kakariko Villages: the original of Ocarina of Time, the Hidden Village, also known as Old Kakariko, and the Kakariko Village of Twilight Princess. Therefore, the Kakarikos of Ocarina of Time and Twilight Princess could be the same village if the Ocarina village was founded by someone named Impa, but not the same Impa that was raised there.
