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.

Liquid Oxygen is crazy.

Really, really crazy. And honestly, it's not in a good or a bad way.

Most Ice dragons in Aquenee's caves are crazy in a bad way; evil, callous demons that perform only the most violent and malicious acts. Some are crazy in a good way, praising a magical flower god that will give them cookies if they commit acts of kindness.

Liquid Oxygen just thinks the air around her is a liquid. She believes all dragons are 'swimming' through the air. She absolutely refuses to believe that air is a gas and that dragons 'fly' about. When questioned about the properties of other miscellaneous things, she will promptly reply that water is solid and that trees and rocks and dragons are gases. Interestingly, she cannot decide about whether ice is a gas or a solid, seeing as it is 'gaseous' like rocks and trees, but it's made of water, which is apparently a solid. Some dragons say that she is the only dragon to ever make Vexen himself cry out of fear of this dragon's thoughts.
