Howling:Eye of Harmony in the Doctor's TARDIS

We all see the Eye of Harmony inside the Doctor's TARDIS in the TV Movie, apparently its main power source. Now "The Deadly Assassin" also features the Eye of Harmony, but there it resides on Gallifrey. Some have attempted to solve this discrepancy by saying that the Eye in the TVM was not the same as in TDA, but a duplicate that's part of all Type 40 TARDISes. But when you think about it, even that doesn't make much sense, because by the Doctor's time, no one on Gallifrey knew the location of the Eye; it had long ago been lost in the ancient past, and was regarded as mostly mythical. So how could the Time Lords have duplicated something they had so little knowledge of? 82.2.136.93 19:55, August 13, 2011 (UTC)
