Re: A Whole New World
I'd say the pylons are tapered for some of the distance down and then just drop off, each edge or level being between 20 to 30 miles wide, the inside of pylons are hollow and with different levels as well accessble by tunnels that wind down to each level.
I like this as well, I'd like to think of this world as having been around for eons with the rise of fall of not only civilizations but entire groups intelligent species with ages in between where there were none.
The idea of monstrous races/gods is definitely something I'd like to use along with races of "deep ones" who "infect" and interbreed with surface races using some kind of dark magick. The "Endless Sea" idea also works toward something else I'd been considering. That this world is one of hundreds or thousands of "worlds". All built on the mysterious pylons separated by hundreds of thousands or millions of miles. Each one could have it's own sun and be surrounded by "planets" and "moons" each also built upon the pylons and each with it's own ecosystem and creatures.
