Froppy

Froppy is a traveling bard from a nameless swampy region. His harp and skull necklace are from the same animal, a species of marsh rat known as Olenkemirgis that he raised from a kit solely to make a harp out of its bones. It's a practice that's been carried out by bards like him for generations. While the bard is taking care of the Olenkemirgis, they are also composing a Last Song. This is the song that is sang to the Olenkemirgis as it dies. The better the song, the better the harp. The harp is fashioned by the bard themself, and the music is plays is mournful and carries a powerful magic that stems from the care that the bard showed the Olenkemirgis during its life and the trust the Olenkemirgis had in the bard.
