Black light rod
From Tardis Wiki, the free Doctor Who reference
Black light rods could be used to feed chronon reactors or, when sufficiently depleted to become black light cores, as part of a Timonic Fusion Device.
A consignment of black light rods were to be sold to Free Time on the orders of the Monan Host in order to draw them out. The Monan timeship containing them was intercepted by Vortex Ops before they could arrive on the Third Moon of Kikrit. (AUDIO: Weapon of Choice)
