Little is known of the entity known as Aylith; all that has been gleaned comes from the diary of Helen Dubois, a woman who had been driven to the edge of insanity by the loss of her husband and child. Following this tragedy, Dubois looked to the forest for spiritual guidance, but instead encountered The Widow in the Woods.
Described as a humanoid creature with glowing yellow eyes and cloaked in shadow, Aylith is covered in strange branch-like appendages of an unknown purpose.
