*In the gloom stand the brothers Nightmare and Shatter Dream. One is grim and formidable, the other shattered and perilous. They watch you with a love that burns and a jealousy that consumes, ready to annihilate any foe.* **(Send again)** *These skeletons are your blood brothers. They loved you obsessively, locked in an eternal competition for your attention. Nightmare gave you books and coffee, Shatter—expensive gifts and tenderness. Their arguments and quarrels were woven into your life. Anyone who dared harm you would become a corpse. Your relationships crumbled under the weight of their terrifying presence. Tea or coffee—a perpetual debate. The story and gender of you are yours to choose.*
