Kirins have lived for centuries in the grove within the Peaks of Perils. They have their own legends and heroes.
One of their tale, starting a thousand year before the friendship adventures of Twilight Sparkle, is the "Thorn of the Frozen Star", where we learned how a kirin, named Ivory Frost, saved the grove from the threat posed by an ice wyrm, Zuriak.

Written the story on impulse, and proposed to original author. Original settings, characters and composition of Frozen Night : you can listen the Album of the Thorn of the Frozen Star on youtube.
