—The Dragon—
An excerpt from "An Investigation into the Cultural Customs of the Wind Kingdom," more commonly known as "Records of Customs and Culture," by Jacob Musk.[Note 3]

The "Wolf" of the Knight of Boreas, the "Lion" of the Lionfang Knight (or "Dandelion Knight"), the "Falcon" of the Knights of Favonius, and the "Wind Dragon" Dvalin have been long regarded as the Four Winds that watch over Mondstadt.
After the Lionfang Knight liberated Mondstadt, the Knights of Favonius was established, and the Knight of Boreas joined them.
The tradition of worshipping the Four Winds was gradually formed in Mondstadt. However, Dvalin, the ancient Wind Dragon, predated them all.
Approximately one hundred years ago, the land was in chaos. Darkness spread, contaminating everything it touched. Barbarians and foul creatures roamed the lands, forcing people to dwell within the city walls.
It was an especially difficult time for Mondstadt. The Lionfang Knight was without a suitable heir, and the Knights of Favonius had lost many of its brave men and women during the bitter wars. During the most difficult of times, Durin, the corrupted dragon of immeasurable power, began attacking Mondstadt.
The prayers of Mondstadt's people awoke the Anemo Archon, and his will summoned forth the Wind Dragon Dvalin. As the last defender of Mondstadt, Dvalin battled Durin with all his might.
The result was clear — Durin's remains still lie atop the snowy peaks to the south of Mondstadt — but the story of how the battle ended was lost in time. It is said that Dvalin ripped out Durin's throat, and together they fell from the sky. Durin's body sunk into the snow while Dvalin was summoned by the Anemo Archon and fell into a slumber.
...
People used to believe that Dvalin would awaken whenever Mondstadt faces a new threat.
But in these times of peace, the belief of the Four Winds has gradually eroded and their temples lie all but completely deserted.
(Citation of unknown origin: By the time the Knights finally discovered that the foreign monstrosity named Stormterror, with which they clashed countless times, was in fact Dvalin of the Four Winds, the enmity that had grown between them and driven them to conflict could not be undone. One can scarcely imagine the betrayal Dvalin must have felt when he awoke after a hundred years of slumber only to find that the people of Mondstadt, whom he had protected with his life, had forsaken him...)
