1st Floor of the Tower

Mostly empty, and alone is 6 kilometers wide, and the ceiling is 30 feet away from the ground. 13 doors are on this floor, one leading to the 2nd floor, another to the 3rd, the 4th, etc all the way up to the 10th. No door leads to the 6th floor, meaning the remaining 4 doors lead somewhere, but only Tera knows. The table is for delectable meals, but sometimes they prepare themselves.
