Photon Drive Segment

A compact, smooth-edged metallic slab etched with glowing amber circuits, the photon drive segment pulses weakly with stored energy. Torvin and Ainu handle it with reverent caution, its critical role in Erato's escape effort making it the most dangerous artifact to steal from the Doctor's TARDIS. The bandits recognize its value immediately—not just for ships, but for Chloris' threatened metal supply.

After: Still in the hall but now the focus of the bandits' attempted theft, its removal temporarily stalled by Karela's proximity
