Burning Clouds
From Tardis Wiki, the free Doctor Who reference
The Burning Clouds was a region of constantly burning gas in the Seventh Galaxy. It was located between Skaro and the Milky Way, causing light distortion which obstructed human observation of Skaro. It was over two million miles wide and anything that entered it was melted by its intense heat.
The visible side of Skaro faced the Burning Clouds. (PROSE: The Seventh Galaxy [+]Loading...["The Seventh Galaxy (feature)"])
