A map of my fantasy world before it's cataclysm

This is my fantasy world. The whole world has a diameter of twenty two thousand miles. The light green area represents a true void of nothing. It is not actually greenish like here, it is nothing! No time or space, and impossible to get into. The dark gray circle is where the sun and stars are, it is a vacuum. The sun of this world is a large glowing crystal sphere that give warmth and light to the world. The stars are much smaller crystals. The moon of the world is the same size as the sun, but with much less light and heat. It was made to move the ocean and keep it from getting stagnant. The land is the green area, it is ten thousand miles across. It gently rises from sea level at the edges to one thousand feet inland. There are four inland seas with islands in the middle, one for each of the primordial interdimensional beings who created this world. In the exact center is a hundred mile wide crystal sphere with many tunnels and chambers inside. It is the palace of the four great beings, and where they meet to rule the world. The ocean is a uniform two miles deep after the continental shelf. The water and air is held in by a nearly indestructible transparent crystal wall that encloses the world. Underneath the ocean and bedrock the world is held up by a foundation of solidified telekinetic energy that also maintains the laws of physics of this little universe. It also has manny tunnels and caverns and a secret control center. The only way into this underworld is through the crystal palace, and with the permission of the great beings. The world has a mild tropical climate with no strong storms or wind or extreme heat. There are also many springs and small streams across the land, although I did not add them as I don't think they could be seen in this.
The world as seen here is in a perfect state, but became dramatically different after the cataclysm!
Now the gods or great beings who created this world are not like the christian god and all powerful and all knowing, they had limites and made mistakes! The laws of physics are similar to our world but gravity and kinetics do work somewhat differently. Gravity always pulls down towards the bottom of the world regardless of the center of mass. More noticable is that in this universe rocks and such tend to break into triangular shapes instead of how they do on earth. This makes the mountains all have a jagged triangular or pyramid shape and rounded mountains are very rare. I'm focusing on the physical aspects of the world right now, but there are some interesting creatures that live there.
So what do you think?

 

Yeah they did not get everything right, for instance the world has a lack of metals necessary for advanced technology and also the sun malfunctions sometimes.

 

Eh, maybe. Thats an interesting idea but I'm taking this world in another direction. It's going to be like a reversed lord of the rings.

 

That actually sounds cool! Anywhere I can read it?
My world will be a medieval post apocalyptic theme, there will be european and asian style.

 

How do I send a pm? I can't find anything about it on here.

 

Thanks, you should check out what the world looks like after the cataclysm!
