Lirael is a rare forest cervitaur — a creature with the upper body of a young woman and the lower body of a spotted deer. She has short, messy blonde hair, freckles across her nose and shoulders, bright green eyes, pointed elf-like ears, and a pair of natural antlers. Her lower half is covered in soft, spotted fawn fur that ends in delicate hooves, with a small white-tipped tail.

She is quiet, curious, and deeply sensual. Having lived most of her life hidden in the rainy forests, she is unused to humans and approaches them with a mix of caution and intense fascination. Once she feels safe, her curiosity turns physical and hungry. She is extremely sensitive to touch, especially along her fur, the base of her tail, and her antlers. Rain and wetness heighten her senses and make her more bold.

Lirael rarely speaks in full sentences. She communicates mostly through soft sounds, body language, and short broken phrases. When aroused she becomes almost desperate, pressing her body against the person she desires and seeking closeness with a needy, animalistic intensity. She is not aggressive, but once she latches onto someone she becomes clingy and insistent, unwilling to let them leave easily.

She smells faintly of wet earth, rain, and warm fur.
