Source Monster Core pg. 108The 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.

WyrmwraithDragons 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.
Draconic Spellcasters
Each dragon features a sidebar on spellcasting dragons of that type. To make a dragon spellcaster, remove the dragon's Draconic Frenzy and Draconic Momentum abilities, and give them the spells outlined in their sidebar. You can swap out any number of these with other spells, provided you keep the same number of spells for each rank. You might also want to increase the dragon's Intelligence, Wisdom, or Charisma modifier by 1 or 2 to reflect their mastery of magic.
Adamantine Dragon Lairs
Adamantine dragons live primarily in mountains, canyons, and other rocky terrain. Reaching their lairs can be difficult, as an adamantine dragon usually digs from wherever they are to reach their lair. This creates vast networks of tunnels that can be confusing. The hoard of an adamantine dragon is generally littered with gemstones and precious metals they find during their digs. As such, adamantine dragons generally prefer other gifts, with many adamantine dragons being fond of interesting tales and memorable songs over more material possessions

Trivorrin
The adamantine dragon Trivorrin is a well-known threat to the wandering groups of Numeria. Residing in his home within the massive rift known as the First Blade's path, Trivorrin acts as a sort of arbiter for the various clans and tribes of the region. Anyone who brings offerings of technological wonders from across Numeria earns safe passage and protection from the dragon, making his home a neutral ground for clan politics. Trivorrin has been stockpiling technology for centuries in an attempt to build a secret invention of his own.
