White Dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can’t bring back the dead. They only eat plants and never kill living things.

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.

Libra was the first and main healer of the Aincrad Clan. He is a very gentle and kind dragon who is friends with the whole clan except for Drakon Attor, whom he holds a grudge against and considers and enemy. Since Libra was always so focused on healing the clan's sick, he never really found anything else to do. He also never found interest in any of the females in the clan until he first saw her, Skye Fantasia, his mate.
