I just want to make sure: you do realise that when I refer to the center of the planet, I mean the point underground half between Cartoon America and Cartoon China, right? Not a place on the surface, but a point at the middle of the globe.
Yeah, I do.
@ waldronate: Thanks for the tip. I'll try it out and see what happens -that or leave it as it is. Well... I'll see what works out in the world building process. I just wanted to know if, with the way the rivers came up, if it was believable and possible.
