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.

Members of the Morphing flight are very close to each other; if they perceive a threat they will defend as one.

That aside, Porthos is a friend of Athos and Aramis and spends most of his time with them. Honest and slightly gullible, he is an extrovert and shows his emotions rather enthusiastically, to the point of becoming annoying to anyone not used to his flamboyant attitude. He means well however, and has an innocent heart, which earns him more friends than enemies.
