Object
Strata Tube
A cylindrical glass vessel embedded in Greel’s time cabinet, its swirling internal layers of energized plasma rotating like strata in rock. The Doctor identifies it as the core component powering the time travel mechanism, its chaotic internal currents exposed when Greel partially dismantles the machine. The tube hums with unstable energy, casting sickly green light across the faces of the onlookers.
