Definition:
An ancient lineage of primordial dragons born during the formation of realms—entities tied not just to elements, but to the literal shaping of worlds. They weren't just beasts of flame or frost; they were living catalysts, used by the cosmos (or the System, or something beyond it) to terraform, ignite stars, stabilize ley-lines, and birth atmospheres. Their battles formed continents. Their deaths seeded magic into the bones of reality.
They were never meant to exist in this current age.
Their extinction wasn't due to war—it was deliberate erasure by cosmic forces or ancient pantheons who feared what they might become.
Pyraethrax, as he claimed, is the one of them.
