Inspired by the Firebringer Trilogy by Meredith Ann Pierce.
In the books, the Wyvern drove the unicorns from their ancestral home many years ago. There is a part though where the unicorns come upon a few Wyvern who lack stinging barbs they want only peace with the unicorns and the unicorns spare them. This is my take on that scene. These are no particular characters from the book, I just really wanted to color a blue dapple unicorn with purple hair.
Line art of the unicorn is in the Coloring Book:[link]
