Earthware Jar Fuel Cell

A simple unglazed clay vessel, roughly cylindrical with wide shoulders narrowing to a constricted mouth, the earthware jar bears signs of hastily applied rivulets of lead solder sealing hairline cracks along its midsection. Emilia holds it steady while the Doctor presses a cluster of violet crystals into its base—pulsing faintly as if resonating with ambient cosmic interference. The clay’s porous surface glistens with a film of violet residue left behind by previous fueling cycles.
