Shalltier is Coal's childhood longki, resurrected as a vampire as part of an infernal pact Coal struck with Lionel. Post resurrection Shalltier is ageless, retaining all of her wounds, memories and body from life. However she was resurrected with deathly pale fur and is hauntingly chilled to the touch. Shalltier has developed long fangs, slit pupils, and is sensitive to the sunlight since being revived. The revival did  something to Shalltier, as she seems more spacey and unpredictable then in life.
