To IndominusCruor: Because I did 1&2 I'm going to hold off on giving more information for a bit (or try to) so other people can mix some things in. I will however clarify a bit. First of the tower itself is quite large, it is supposed to be the setting itself, so even at its smallest the surface area of the sides is probably worth a continent in and of itself.

Second I left everything else vague on purpose. What is at the bottom of the tower? I don't even know if the tower has a bottom, or how far one would have to travel to reach there, let alone what you would find there. I hope some thought goes into that before it gets formalized, but at the same time I don't intend to be the one to do it.

I'm big on the community aspect. As much as I am over analysing JoshuaZ's addition for possible future problems (I found very little by the way).
