Ice Dragons are fierce predators who hunt using their extremely cold breath. The breath of an ice dragon can freeze its prey solid in seconds. The body of an ice dragon is so cold that icicles will form along its skin no matter the outside temperature.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

The Bone Chiller, or Chiller as her friends call her, is a young and flamboyant Ice dragon of SL's cave. She is charismatic and fiery, the opposite of what her name suggests. She was simply named from her parents, an Ice dragon and a Black Marrow.

She is known in the cave as a sturdy, motherly force, and often occupies herself with caring for the hatchlings while their parents rest. She enjoys playing with the young dragons of the cave, as it reminds her of when she was a young one.

Chiller isn't afraid to express herself, and she does as she wishes. She inherited her mother's ferocity and forwardness. Dragons admire her perseverance and determination, and when she puts her mind to it, she can accomplish anything.

Chiller is naive in the terms of love, as demonstrated by her last affair. She fell in love with Reaper, a mysterious Cavern Lurker, and was torn when he had to leave, especially when she had Chilly Rum. Each day she wishes to see him again, but her prayers are in vain.
