Ancient Horologe

The Ancient Horologe was a very delicate instrument linked to time itself that measured the passage of time across different dimensions. Crafted like an ornate clock by the master chrono-smiths from the older worlds, it was given to Lord and Lady Tubbs as a wedding gift from the Doctor and had pride of place in the Clock Room of Croxton Hall. It was damaged when a thief dropped it in a scuffle with Lord Tubbs. As a result, a fracture in time was created displacing those nearest to it into a different kind of time. (DWAM: 13 O'Clock)
