Guardian Dragons have large shields on the end of their tails. Although the shields appear to be heavy, they are light, yet nearly unbreakable. Guardian Dragons use their tail-shields, as well as their wings, to deflect attacks and protect others. Often, they will guard the eggs and hatchlings of a nest while others are away. They are generally peaceful, and will not retaliate unless necessary. They have no need to forage or hunt, as they are fed by those they protect.

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.

Evac is on of the few Dragon's that Kanakha has raised that does not reside in the Valley of Kan, nor is he under the government of the Order of Kan. He lives in a far a way place, guarding the mythic Secret Scrolls of the Twin Valleys of Penath. It is rare that Evac ever leaves this secret place, and only Kanakha and Rune (leader of the Valley of Frozen Forest) know his actual location, for they are the two leaders of the Twin Valleys. Evac is sometimes paid a visit by Kanakha, who flies on a different dragon via a different route every time. Evac apreciates the visits very much, and sometimes wishes to return to Kan Valley, but he knows his sacred duty is to guard the scrolls.
