Tent City
From Tardis Wiki, the free Doctor Who reference
Tent City was the home of the Unnoticed. It was located inside the photosphere of the Earth's sun. The tents were made of superstring taffeta, so the occupants were unaffected by the external environment. When the temporal closed circuit that created them was completed, the Unnoticed were unmade and Tent City ceased to exist as well. (PROSE: The Book of the Still)
