User blog comment:Grimraven/Players or Suspected Players in the New World./@comment-80.213.121.95-20150922114118

The dryad Ainz in the forest, in the drama cd, said he met the "7 heroes" about 200 years ago which ws at the same time the thirteen heroes were exploring and were alive. Could they be the exact same people? Just not all at once. The dwarf seems to have founded the dwarven kingdom after slaying a frost dragon in the Azerlisia mountains.

I believe the demon gods were simply strong New World heteromorphs and not NPCs and players.

Marine Girl is most likely a NPC (with good karma), I mean, whatperson stays at the same plays for so long doing absolutely nothing? And don't say they are just lazy and won't move for 100s of years! Players (A.K.A humans in the Old World are more comfortable being social and on the surface, and they wouldn't waste their life under water unless they had a reason). If Marine Girl is immortal she might as well be a NPC, I highly doubt she'd be a heteromorph, humans were the most popular ones. And Ainz and Nazarick are meant to be unique.
