(ceilings)
The blank stone walls support the enchanted ceiling. There are four walls for every ceiling. The walls have to be blank, or no one will notice the ceiling. The ceiling is made of a few beams of wood. The walls are made of stone and brick, so much solid rock. Walls last while ceilings lose their luster and must be repainted, replaced.
But the walls will always be blank
Is it a fair trade?
