Large Hard-Shelled Egg from the Mining Crevice

A massive organic egg protected by an unnaturally thick shell, roughly the size of the Doctor’s head, with a hard, pale exterior marred by veins of sickly green streaks. It bulges slightly at its crown, where the shell appears thinner—perhaps a sign of recent hatching or impending birth. Jo Grant recoils at the sight, calling it out immediately as an egg, while the Doctor handles it with unusual gravity, sensing its potential to expose the hidden horror contaminating the mines. The shell feels unnervingly warm despite the cold crevice, hinting at its unnatural origin.
