Yarrow the Sprite
(Open images in a new tab to view full-size)
Yarrow is a 270-year-old sprite. Like others of his species, he possesses healing and protective powers, which he uses to protect the forest in which he resides.
Sprites are thought to be solitary creatures, and leave their parents to find a new territory as soon as they reach adulthood. When Yarrow started on his journey to independence, he found an abandoned cottage in a forest unoccupied by other sprites and decided to claim it. He found himself journeying to the nearby town of Wynwood and became fascinated by human life. The humans were wary of him at first but came to learn his presence was no threat to them.
On one trip to the market, he bought an unsuspecting bag of holding from an unsuspecting merchant. That same night, as Yarrow slept, a domestic imp named Jesper would emerge from the bag and start exploring his surroundings. Alarmed as he was, he didn't send Jesper away.
With Jesper looking for some new sense of purpose, and Yarrow being rather lonely on his own for the last hundred or so years, it seemed like fate.
