Behind the scenes

 * City of Devils and The Scales of Injustice, both by Gary Russell make reference to Endurance, Nicholas Briggs' AudioVisuals story about a 1920s Antarctic expedition which finds a Silurian city. Nicholas Briggs' Frozen Time functions as a sort of sequel to the story, though it replaces the AudioVisuals Doctor with the Seventh Doctor and Silurians with Ice Warriors. (Although the reference in City of Devils still makes sense.)
