Teleport disk
From Tardis Wiki, the free Doctor Who reference
Teleport disks were a form of nanotechnology. Each disk was only a few centimetres in circumference and acted as a point of transfer for an individual. The disks let their users avoid threats by moving swiftly. When activated they emitted a red cone of light with a bright white light at the centre. Farrian deployed the disks in their invasion of Ballustra, releasing large numbers into the area around their CVE. (AUDIO: The Invasion of E-Space)
