'Among the hardest, most bedazzling of substances born underneath the earth, the diamond nonetheless has somewhat of a stately manner, colorless and stoic next to all the multicolored stones with which it coexists. But what it arguably lacks in outward beauty it makes up for with its uses in the sprawling industry of death which Master Hades oversees. Within the Master's House, the diamond always holds a special place; its hardness, helping excavate the stone and carve out all the likenesses and monuments encapsulating many ages past; its shimmering facets, hewn a certain way, absorbing little bits of light that can remind even an ancient shade of what it meant and what it means to live.'
