Stealth Dragons are used by Vikings as riding dragons, in particular for military stealth or reconnaissance operations.

Traits and Abilities

Stealth Dragons are just that - stealthy. Their colors are constantly matching their environment, making them effectively invisible. Though the dragon is invisible, its riders aren't. This is circumvented by seating riders between the double row of large aerodynamic spikes along their backs, thus masking the riders as well. It is not clear whether the Stealth Dragon changes color at will, or if the change is unconscious.

Additionally, Stealth Dragons are made stealthy not just visually, but also through sound. These dragons can slow their heartbeats that another dragon might hear, as well as flap their wing silently while flying.
