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.
Giafcaz Thuwed is said to be descended from gods, much like his father, Xecco Couv. Thuwed is a name which is very special to most tamers and carers to dragons. These "gods" are actually dragons who had been befriended by a man known as TJ, and are perfectly normal, making Giafcaz Thuwed just as normal. However, he was the first dragon of his kind on his scroll, as well as being father to Ksezi Thuwed, and that makes him a well-known and favoured dragon on his scroll.
