Publisher's summary
While investigating a strange energy in Carbury, the Tenth Doctor and Donna Noble are pulled into a different dimension, smashing a giant hole into another world in the process.

As the magic of the hidden dimension slowly seeps out, the Doctor and Donna find themselves in Camelot, where a young squire, Arthur, comes to their aid, and when the Doctor is mistaken for Merlin, they are swept up in the glamorous and daring legends of the Knights of the Round Table.

But something far more menacing has been awakened. Caught in an ancient battle for power, Donna and the Doctor are sucked into a dangerous game. As each move is made and time spins faster, the Doctor must find a way to seal the rift before an unimaginable power is unleashed and the universe is laid to waste.

 * The Seventh Doctor encountered individuals related to the King Arthur legend, as they crossed dimensions in an invasion of Earth in Carbury. (TV: Battlefield) This account was heavily discussed and referenced by the Tenth Doctor and Donna.
 * The Eighth Doctor encountered individuals related to the King Arthur legend, called himself Merlin and created messages for his past self. (PROSE: One Fateful Knight) Other accounts also claimed that a future, red-haired incarnation of the Doctor also became Merlin, although the Eighth Doctor believed it was merely another Time Lord posing as the Doctor. (PROSE: Battlefield, Happy Endings, et al.)
 * The Tenth Doctor claimed that he was once called Merlin by King Arthur. (COMIC: Fugitive)

 * The Doctor uses a crank handle to open the TARDIS door. (TV: Death to the Daleks; AUDIO: The Gift)
 * The Doctor refers to his time in his Seventh Incarnation as being all mysterious and manipulative, the rebellious phase one goes through when turning a thousand years old, and slipping notes to himself from the future would be something he would have done.

(PROSE: The Room With No Doors).
 * The Doctor encountered the real Spear of Destiny in his Third Incarnation, battling the Master for possession of it. (PROSE: The Spear of Destiny)
 * The Doctor compares the quest for the Shards to his first search for the Key to Time, involving collecting six things that were hidden in six different parts of the universe and could disguise themselves as anything. He mentions that one piece of the Key was a planet, (TV: The Pirate Planet) one was a person, one was swallowed by a giant god octopus, (TV: The Power of Kroll) and he had to deal with four versions of his companion including her, her double, her robot double and her double’s robot double. (TV: The Androids of Tara)
 * The Doctor observes that Lancelot reminds him of an old companion of his, a science teacher who is now in his eighties in Donna's time. (TV: An Unearthly Child et al) Donna responds that the gorgeous ones always turn out to be either married or actually evil alien spider lackeys. (TV: The Runaway Bride)
