"YOU WILL CHOKE AND DIE ON THE BONES OF YOUR PETS, TIME LORD, AND YOUR CHILD WILL BE UNBORN. REJOICE AT YOUR FATE, AND GIVE OVER TO ME!" came the sour thick echo through the bone-covered cavern, the terrible voice of Shub Niggurath, who had consumed his brethren in the Long Before.
As the Doctor's limbs quivered from loss of blood and the sheer terror of his situation, the sound of rattling began to fill his ears.
Slowly, so slowly, and yet so swiftly too did the bones that littered the floor of the ancient catacomb squirm into motion, rising into mid-air to form titans of fixed-together tarsils and skulls, tibias and phalanges, rib cages and spines.
"My baby, my baby…" he sobbed, clutching his dilating belly as another contraction tore him, ripping through his bits, leaving him breathless.
"SHALL I SING A LULLABY BEFORE I EAT YOU, TIME LORD?" Shub Niggurath hummed from everywhere and nowhere, as the bone titans curled around the Doctor in a quickly closing ring.
