Official Description

These Dragons are the silent but strong type. They're more comfortable in the background, but are always ready to swoop in when someone or something they care about needs help.
As in life, the Thornridge prefers to stay back and fight from the shadows. It will only go to the front lines if it senses a comrade in danger.
