Dragon Souls (Primer)

Earth; mid-late 21st century; Humanity occupies the surface completely unaware of an underground civilization of dragons known as the Subterrains of Drekiheim, due to its protection by dragon magic. Within the bowels of this grand subterranean ecumonopolis lies cultures and clans with lives of their own, complete with an internet-like collection of knowledge known as Grand Archive Access, powered by an ancient artifact known as the Grand Archive.
Recently, dragons reincarnated from human stock have been regaining their human memories due to use of G.A.A., and as such may bring to bare the catastrophe that dragons hide from the surface to avoid: the extinction of dragonkind by human hands.
The story follows a man from pacific-cost America after dying in his sleep from complications due to old age and being reincarnated as a dragon. Upon hatching, his is immediately aware that all of his human memories intact; an oddity given that most who regain any memories at all don't until much later in life. Fortunately for the rest of dragonkind, he also wishes to avoid the extinction of a what he believes to be such magnificent creatures and cultures worthy of survival.
