The Quiverpain egg has the appearance of jaggedly spiky ice in a sea green color. The tips of the 'ice crystals' are a reddish-purple color.
Hatchling to Adult
The Quiverpain dragon has the general physical appearance of a standard Shivertooth. However it varies from the standard ice blue colors. Instead Quiverpains are a sea foam green color with royal purple vertical stripes along their body, as well as on their spines and wing tips.
Gobber portrays the Quiverpain as an intelligent and crafty dragon. In order to get a saliva sample from a wild Quiverpain, Gobber approaches the dragon in a friendly manner. Simply by having Grump fire on the ground, the wild dragon understands that he was asking it to do the same.
Behavior and Personality
In addition to being 'tricky', Quiverpains also appear to be at least somewhat solitary dragons, building nests for only themselves. They don't seem to be particularly territorial with other dragon species, though it is unknown how aggressive they might be with others of their own kind.
Quiverpains may also be able to tolerate more temperate climates than standard Shivertooth dragons. Standard Shivertooth dragons are typically found in cold arctic type climates, whereas at least one individual Quiverpain lives on Healer's Island, which is considered a more temperate location.
Despite the Quiverpain's official description stating that both the saliva and scales have healing properties, it is implied in Gobber's Journey text that only the saliva is useful. Silent Sven's throat is healed with saliva, and Gothi rejects the scales that Gobber brings her.
