After debating on it on and off for nearly a year I finally decided 2 commit to shipping with an OC </3 would not have happened if I hadn't designed Erinys and accidentally made the perfect s/i for it though. Anyways here's some messy refs (+ a bust sketch of Llyr I made for his TH)
Llyr is inspired by / heavily based on the short story The Harrowing of the Dragon of Hoarsbreath by Patricia A. McKillip
