The air in the apartment was thick with sadness. Marcus couldn’t seem to shake the feeling of being utterly alone. Her laughter. Gone. He couldn't believe it. He wandered through the rooms, a ghost in his own life.

His nephew, Noah, was visiting. Noah loved to draw. One afternoon, Noah presented him with a drawing of a creature made of shadows, with glowing yellow eyes.

“This is Umbra,” Noah said matter-of-factly. “He's waiting for you.” Marcus froze, the world tilting slightly. Umbra. His childhood protector, the embodiment of his anxieties, now brought to life again. The sheer unexpectedness was stunning.

He stared at the drawing, a sudden wave of nausea washing over him. “He… is he?” he stammered, his voice barely audible. Noah nodded, and Marcus was swallowed by the memory.
