Alien Artifact Egg

A smooth, egg-shaped alien artifact of unknown origin and purpose. Its polished surface reflects no light, and its lack of seams or features initially makes its function unclear. Marked into quarters by faint seams that catch dim light, it stands roughly man-sized and serves as improvised cover during an android ambush. The Doctor recognizes it as significant enough to shield behind, while its presence among freshly minted military coins suggests a connection to the android conspiracy.
