Kestril possesses a deceptive, shifting physicality that creates a sense of constant, slow motion. In his preferred form, he is a man of slender proportions with skin the texture of aged parchment. His eyes are his most striking feature: the left is a vibrant copper while the right is a deep, unblinking sapphire. He moves with a rhythmic, hypnotic swaying motion as if walking through invisible water. Contradicting his elegant attire, his hands are covered in thick black ink stains that never seem to wash off despite his meticulous grooming.
