Moonbriar

Rabbitkind is afflicted by the Great Culling—a divine calamity purging them through war, famine, or plague every generation. You play as Fern, a young girl living under the harsh rule of the evil Nightshade. When you're revealed as the potential Seed—chosen to lead rabbitkind through each purge—you must defy the established order and forge a new destiny for yourself and your loved ones before Moonbriar is consumed.
