Visualization

After being fished out of the hole and Hans carrying the unconscious nephew for three days, they found the center of the earth.  When the nephew wakes up he can smell the fresh air, hear the ocean and immediately asks "How did we get out".  The uncle explained that they did not get out at all, and that they had just reached the center of the earth. The sea he named The Central Sea.

 

The Central Sea could go as far as the eye could see with huge dark shapes in the distance.  Sea shells would line the shores.  An unknown light source lit up the whole area.
