User blog comment:Raltin avarr/Theory on The Creation of Dragon Metal/@comment-25345260-20130503105335

I'd say while the Blood theory for the metal is interesting, it's unlikely. We've taken lumps of the metal from Tormented Demons summoned by Lucien to make platebodies.

How did it get on the demons, if there are so few Dragonkin? It wasn't some form of weapon. We didn't put blood into the metal to make the platebody.

It's believed Dragonmetal comes from another realm, likely the one the Dragonkin originate from. When they were brought to Gielinor, they brought the metal with them. Since it doesn't originate from here, there are no ore veins, and very small amounts of it.

And, I always speculated the Water Lizard part was a reference to Jurasic Park, where the scientists used bullfrog DNA to complete the Dinosaur DNA to create a sort of Hybrid.
