Ancient Dragons.
After the World was born, primeval beings borne of Steel Strength crystallization became the shared ancestors of all beings, the origins of bloodlines. The very reason for their birth was to spread the seeds of life, so that the empty, barren World that had nothing could be filled with life.
In different worlds, primeval beings had different names—World Trees, Tortoise that Carries the World, Realm Serpents and so forth. The reason why Ancient Dragons were named as Ancient Dragons was because their most numerous species of descendants were known as Old World Dragons. Hence, the Ancient Dragons that had a similar form became known as Ancient Dragons.
