Where the Dawn Rests

This myth goes hand in hand with the story of the Lighthouse of the Winds, though it's often told on its own. The story of Dawnfall's mountain is recited every year at Orest, the yearly celebration of Orellia's founding.

Summary

The gods (or sometimes only Elder Sister) led the settlers of Lialin to their new continent from the mists of uncertainty, but the blessing did not end at the shores. Instead, every morning, the dawn's light highlighted the place they were meant to reach - the origin of the Dawn, and where it came to rest.
Though the settlers at first thought to find the gods there, they instead found another light, guiding them up the craggy rock faces and winding paths of a lone mountain surrounded by fertile foothills. At its rolled peak, Orela founded the city that would become known as Dawnfall, and with it, the entire Orelli monarchy.
Some variations include a message given to Orela Dawnson and the other settlers that detailed the mountain's importance to the gods. Examples include that it was where the gods were born, that it was where each god first came to be during their Godswalk, that it was The Stone Man's own home, and more.
Dawnfall is still regarded as the place where humans can be closest to what is holy. Legend says so long as no other mountain looms higher, the country of Orellia will stand.

In Literature

A novel claiming to be historically accurate was published under the same name, Where the Dawn Rests, and was supposedly compiled from Orela's personal journals as well as other 'eyewitness' accounts. Given the book was published nearly a hundred years after the fact, that validity is doubtful. The book also has no known author, being credited to 'Time and its Passing.'
References to a large mountain are typically used in Orelli fiction to convey importance of a location, and novels based on political intrigue are commonly placed in Dawnfall itself.
In rarer cases, such as lesser novellas or political tales by Theoli revolutionaries, it's used to indicate a sense of over-importance to one's self or others. Phrases such as 'one who blocks the sun' are less about the individual's physical stature, and more their arrogance.
While few examples of Aheri literature have ever left the islands, one philosopher is credited with musing that due to the islands' mountainous regions and general elevation, were they perhaps as important as several Dawnfalls, all clustered together? This interpretation is regarded by most who have read it as satirical.

In Art

Placing the peak of a singular, large mountain in the background of a landscape or other work of art is a way of conveying 'endorsement by authority.' That authority could be intended to be the Orelli monarchy, or The Stone Man themselves, as any stone structure can be attributed to them.
Portraits of Orela usually show him on a peak of some kind to reference the myth - a trend that has continued in portraits of his descendants.
