Mountain Goddess

"The last eruption blocked the way into the village. I fear the mountain goddess must be very angry..."

- Goron

The Mountain Goddess is an unseen deity mentioned in Spirit Tracks by the Goron tribe that lives on the Mountain of Fire in the Fire Realm of the re-established kingdom of Hyrule. A shrine, the Altar of the Mountain Goddess, is built in her honor just beyond the boundaries of Goron Village and is a place of worship for the Gorons, namely their appointed ambassador to the shrine, Kagoron. Few others are permitted to enter her shrine of their own accord, though an exception is made for the young hero Link when he comes to Goron Village and is told to meet with Kagoron.

Link goes to the shrine to meet with Kagoron to inquire about how to meet with the village elder and learn the location of the Fire Sanctuary so that he can restore the realm's lost Spirit Tracks and reach the Fire Temple high atop the mountain. The Gorons send Kagoron to pray to the Mountain Goddess when the mountain becomes violent and unstable, hoping that their patron deity will help calm the mountain's rage (in reality the work of a monster named Cragma). Beyond this, not much is known of the Mountain Goddess's true nature or even her true identity. She is obviously well known amongst the Goron tribe, but no light is shed upon her origins or who she really is within the game, though she appears to be the one the Gorons turn to in times of crisis.

Theory
Though the three Golden Goddesses that crafted the original Hyrule are not seen or officially mentioned in the game, there are some who believe that the Mountain Goddess may perhaps be another title for the Goddess of Power, Din. This stems from Din having crafted the world's red earth and her strong alignment with the element of fire and with the Goron race itself. The Gorons of the original Hyrule had knowledge of Din's existence and a statue of her existed on one of the islands of the Great Sea, meaning that her existence was still known of by some within the world on the surface of the Great Sea. A number of Gorons were shown to have survived the Great Flood in both and, meaning that they likely migrated to the new Hyrule upon its discovery and foundation. If the Gorons that survived the Great Flood and migrated to the new Hyrule still knew of Din's existence and still held her in high regard, it is a possibility their descendants may have chosen to pray to her under the title of the Mountain Goddess.

Trivia
In the European version of Spirit Tracks, Gorons speak of Mountain Spirits instead of a Mountain Goddess.
