Quantum rune
From Tardis Wiki, the free Doctor Who reference
Quantum runes were objects used by Vandosians that could tell when and where a spirit had been reincarnated. One Vandosian spent five decades divining the location of Shogalath's reincarnation as Peckham Hospital, 7 January 1979 at 3:50pm, using quantum runes. (COMIC: Mr Nobody)
