The powerful adamantine dragons are one of several dragons known as skymetal dragons. The innate magic that flows through these dragons causes them to draw particular metals to their bodies like magnets or, in some cases, naturally grow these skymetals on their bodies. Adamantine dragons begin their lives with tough scales that are naturally replaced with thicker and even tougher adamantine plating as they grow older. Adamantine dragons are typically steadfast and loyal. Once they commit to a certain purpose, changing their minds is nigh impossible.


Dragons come in myriad forms, with many having magical abilities or connections to magic. Some dragons draw greater power from magic than others, allowing them to manifest abilities or alter their physiques with prolonged exposure to magic. These dragons become more powerful as they age and strengthen their connections with their magical origins. Scholars debate the classification of these dragons, with some preferring the name magical dragons and others using traditional dragons due to their connection to specific magical traditions. Regardless of their names, these dragons share a number of characteristics: their ability to tap into magical energies, intensified might and cunning as they grow older, and an inclination to hoard vast amounts of treasure and wealth.
