Only the dragonkin know the process to create true dragon armour. Others can perhaps manipulate the base metal, orikalkum, but they lack something in the process that turns the metal into true dragon metal, a far stronger source. In aeons past, on their original world, dragon armour was worn by the Ortius Chen, the mighty warriors of what was once a great dragonkin army.
In the revision before, this army swept across worlds subjugating the other races, few in number as they were. The other races were weaker, smaller, and less self-aware, a trait that made them perfect to work in dragonkin mines. There life was harsh, cruel and often short, and the dragonkin masters had little sense of pity.
All, save one.
Nastralla was a seer whose visions pierced the flow of time and allowed them to witness the entire lifespan of the dragonkin’s cruelty. They saw worlds before dragonkin invasion and the worlds after and they found it abhorrent. They were not alone.
