Silver Dragons are arguably one of the most beautiful types of dragons. They live in high altitude habitats such as mountains. Male Silvers hunt and eat meat. While not as beautiful or radiant as females, silver males possess better physical attributes, such as strength.

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.

Caisteal, son of Shawe and Caithrin, has gone back to his father's homeland. After searching the length and width of the old island, he has chosen an abandoned, ruined castle on the north-west coast of Ireland as his home. In what was the great dining hall to it's previous inhabitants, Caisteal has clawed out a tunnel deep into the earth and rock, making himself a den.

Humans living in the towns and scattered farms close by speak of a cursed treasure in the old castle: at clear nights a silver glittering can be seen within the castle's crumbling walls, yet those that ventured inside to claim the prize have never returned. Little did they know that this is no great treasure, but moonlight reflecting of the scaled armour of a dragon who appreciates his peace and quiet. Caisteal's silver body is long and slim, yet incredibly strong. He never seeks battle or murder, but when he feels disturbed or threatened, his sharp claws will lash out at the culprit in a fraction of a second.
