Long-lived as dragons are, some remain in the world, long after heartbeats falter. Necrotic energy instead of blood provides the animation for these undead dragons.

The bone dragon is created from the remains of several dead dragons to form an animate and dully sentient whole. A Dragon does not choose to become a bone mongrel. Once transformed into the undead skeletal monstrosity. The creature hates its existence, and mockery of life, but due to the ritual’s evil nature, cannot end its animation.

This skeletal dragon head has a malevolent light burning in its eye sockets.The bones forming the creature's head clearly do not match, and the dragon’s skull shows rivets where the lower jaw and various horns have been attached.
