Description

There was an old artifact beneath the waters where the energy soaked through. The patterns of the waters personifies the yaks, and an unknown text is written on the corner. Read the text and solve the mystery of the artifact.

"The yaks nurtured by Azunak
have matured.
The fields of each town have yielded good harvest
and the barren lands have grown vegetation.
Yet it came at a cost. The first yak lost its sense of hearing
and could only hear loud shouts.
The second yak has to live eternity with a foul stench.
The third yak felt the pain of starvation no matter how much it would eat.
The fourth and youngest yak was bound to grant the wishes of humans,
not being able to ever leave them ever again."
