Mountain of Serenity
From Tardis Wiki, the free Doctor Who reference
The Mountain of Serenity was a location on Gallifrey. During the First Segment of the Last Great Time War, a munitions factory was located beneath the mountain. It was the site of a Dalek attack. The Daleks were defeated when Tahl detonated explosives inside the mountain, destroying and burying the Daleks. (PROSE: The Stranger [+]Loading...["The Stranger (short story)"])
