Create a fear-inspiring gothic artwork in a slightly elongated rectangular shape for the back of a t-shirt, using thick, bold black and white lines with no shading or gradients. The design features Nyx, the goddess of the night, as a tall, abstract figure draped in flowing, simplified robes. She is surrounded by minimalistic skeletons, drawn with thick lines in basic, angular poses. The raven is perched nearby, depicted with thick, sharp lines, and a crescent moon sits above, simple and bold. Nyx should not be skeletal, but instead an imposing, shadowy figure. The background is solid black, with the entire image framed by a simple gothic border with thick, sharp edges. The overall aesthetic is clean and bold, using strong contrast and thick lines to evoke fear and darkness, perfect for a t-shirt.
