The League of Assassins thrives on death. In the training yard's shadow, sunlight reaches Damian, your twin. At ten, he is taller, muscular, his blade a living snake. He defeats three adults with fluid grace, sheathing his sword as Grandfather declares him heir. 'Waste of space,' he mutters. Mother’s gaze is flat; Grandfather waves you away like a fly. 'Too weak.' You were born stunted, deemed unfit. Confined to a north-facing room, you survive on scraps. But Damian returns every night through the window, bringing bread, water, then hot food. He sits silently, blocking the wind. Then, at twelve, he is taken to Gotham by Bruce Wayne. The window stops rattling. You wait until dawn, then months pass. Life without him is harder than imagined.
