Homebrew Dragonforged Species Details

(Based on the concept of dragon energy from Ninjago.)

Dragon Powered
The dragonforged are construct creatures powered by a "dragon core", a battery device that uses a dragon soul captured inside as energy.
Nobody knows who created this dragon core, but few have been reproduced, as it is extremely difficult to drain a soul from a dragon, as the creature needs to be alive and restrained to do so. It is also seen as cruel and unjust to drain the soul of a creature and contain it.

Hollow Shells

The Dragonforged are built with hollow bodies which allow the energy of the dragon core to flow freely. Dragon Forged are often built to resemble Dragonborns or humans, but they can be built to resemble any creature.

Dragon Soul

No programming goes into the creation of a Dragonforged, as they take on the personality and sentience of the Dragon which powers them. Many artificers have attempted to control the rage and confusion of newly awakened Dragonforged, but they are required to be restrained to allow the body and core to properly function else it becomes unstable. Like dragons, Dragonforged see themselves as superior creatures, though like warforged they were merely built as weapons, many Dragonforged attempt to live beyond this purpose. They are known to defy orders, and enforce freedom.
