Hillkind's ancestors were the first humans to gain wisdom after the Guidance descended and migrated north.

At that time, the divine seat of the God of Fate had already descended, but the brave sojourners knew not what deities were—all they possessed was mere foolhardy courage. However, the owner of that divine seat was at their destination: the proud, fallen God of Fate, Godo.

The traveler's overreach offended Godo, and the latter decided to prevent the former from entering his domain.

Facing the chosen ones blocking their advance, among them the sturdy Glorat stepped forward, proposing a duel with Godo. The arrogant Godo regarded the ordinary human before him with disdain and accepted his request.

Glorat's swordsmanship exceeded Godo's imagination, and the latter was defeated and slain in that duel. On that day, falling stars illuminated all of Ragriff.

Upon hearing this, the furious Riven C. Majesty cursed the travelers, which is the origin of the mountain vassals' appearance today. The authority over Gado's fate lay in the hands of the only God at that time, Alice. This also made the latter the only God to possess multiple authorities.

However, even the curse of the gods could not kill the brave travelers. They made their home in the mountains of the far northern Ragriff, multiplied, and thrived into a civilization of their own, giving rise to Cysindera and other outstanding figures.

Later generations of humans failed to recognize their own kind, instead calling those who lived among the mountains—and thus came to have faith in Ourea—"the mountain's subjects." This is the origin of the title "mountain subjects."

山臣的祖先是指引 降下后第一批获得智慧，向北旅居的人类。

彼时，命运之神的神位已经降临，但勇敢的旅居者不知何为神祇，他们所有唯有一腔愚勇。然而，那神位的所属正在他们的目的所在，骄傲的，陨落的命运之神戈多 [Godet].

旅者的冒进触犯了戈多，后者决定阻止前者进入自己的领地。

面对阻拦他们前进的被选中者，他们中的健壮者，格洛拉特挺身而出，提出与戈多进行决斗。傲慢的戈多对眼前的普通人类不以为意，接受了他的请求。

格洛拉特的剑技超乎戈多的想象，后者在那场决斗中落败身陨。那天，陨落的星辰照亮了整个拉格里弗。

闻讯，愤怒的瑞文•C•莫杰斯塔 诅咒了旅者们，此即今日山臣外貌的由来。戈多命运的权柄系于彼时唯一的受位者Alice 之手。这也使得后者成为唯一拥有复数权柄的受位者。

然而，即使是神的诅咒也没能杀死勇敢的旅者们。他们在拉格里弗极北处的群山中安家，繁衍，生长出了自己的文明，诞生了凯辛德拉 等杰出人物。

后来的人类们并没能认出自己的同类，而是称在群山中生活进而形成了对俄瑞亚 的信仰的他们为“山之臣民”，此即“山臣”这一称呼的由来。
