Yemma has a desk made of mahogany. Not just any mahogany, either. This mahogany is from the planet of Malchior 7, where the trees are three hundred feet tall and breath fire! It is from these trees that his desk was forged two thousand years ago, using ancient blood rituals of the Malchior people. Not only does it make his desk NIGH INDESTRUCTIBLE, but it can bend the fabric of the universe itself!
Also, it's a very fine material. Very expensive.
