Epicentre

From Tardis Wiki, the free Doctor Who reference

The Epicentre was an abandoned industrial complex in Manfold where the breakdown of the City of the Saved's defense protocols started. This occurred due to Antipathy's emergence from Lon Shel in this location, and as a result is where Lon Shel was kept prisoner, as well as all those who were resurrected after being killed by potent weapons.
