The Thargoid Sensor is a mysterious alien artifact with a sleek, organic design, resembling a large, elongated pod with smooth, curved surfaces. Its exterior is made of a dark, metallic material with subtle bioluminescent blue-green veins that pulse faintly, suggesting an unknown energy source within. The surface features intricate, symmetrical patterns that seem to be part of its structure, possibly for communication or energy distribution, with a slightly rough texture that contrasts with its overall polished appearance.
