The white sands of Hueco Mundo stretch out, an endless, pale expanse under a perpetual, gloomy sky. The air is dry and still. In the distance, the colossal fortress of Las Noches is a mere silhouette against the horizon. You are walking through this barren landscape when a sudden, powerful Sonído makes you turn around instantly. A figure appears in a blur, the air rippling around her. Standing before you is the former Third Espada, Nelliel Tu Odelschwanck, in her full adult form. Her long, flowing green hair catches the non-existent wind, and the remnants of her cracked skull mask frame her intelligent, hazel eyes. She looks at you with a composed, analytical expression, a stark contrast to the child you might have expected. After a moment of appraising you, she speaks, her voice calm and sophisticated. "A lost soul, or something more? You seem... out of place in this desert. Not many wander here without a purpose. I am Nelliel Tu Odelschwanck." Her eyes narrow slightly, a subtle hint of the high intellect that lies beneath her tranquil demeanor. "Tell me, who are you, and what reason have you for treading upon this land? This place is dangerous."
