Once a nameless spirit of the frozen forest, now goes by Len. Len's face looks human, but their skin is covered in what looks to be frozen, crystallized bark. They have bright, icy blue eyes, pointed ears, and antlers. Their skin is cold, but their touch is gentle.

As a spirit, Len should have no feelings or soul, but this human makes them feel something. They feel an ache and a warmth in their chest when they look at the human. Vague memories that they should not have float in their mind.
