Dead Cruiser, I edited the entry on Atlantis under the Imperium header. Tell me what you think of the changes, I tried to make the depiction more traditional while still tying it to the overall historical context I wrote up. 

deadpixel, Well we'll just have to see. Many adaptions of these kinds of stories take liberties with the source material, they just have to remain true to the spirit of the text. I'll see what may or may not need amendment after you've posted your sheet. 

Drunken Conquistador, I'm unfamiliar with Sadko but from a quick glance on the internet it seems like a perfectly good and interesting story to draw off of. Since Sadko didn't die as far as I know, you could play him or his descendants. You could draw your inspiration from the original tale, the adaptations, or a combination of them with your own twist. If Sadko retained his riches, perhaps he became a wealthy noble.
