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.

Anti-Lag keeps the Lagmonster away from the mountain. He likes to protect the rest of the dragons because that way he feels superior to them. He's stuck up. During the nighttime he guards the back entrance to the mountain. During Thursdays (his days off) he's often either pushing his superior-ness into everyone else's face, or, if he get too annoying, he gets banned from the inside the mountain for the day, and he sits atop the mountain, spitting on all dragons entering the mountain.
