From publisher blurb: Celebrating the 50th anniversary year of Doctor Who, this Sourcebook explores the Sixth Doctor’s adventures on Earth and beyond. With detailed information on all the allies, enemies, aliens and gadgets that he encounters, as well as examining each of his adventures, the book contains a wealth of material for the Doctor Who: Adventures in Time and Space RPG, and is also a fact-packed resource for fans of the show! After sacrificing his life to save Peri in the Caves of Androzani, the Doctor regenerated into his most flamboyant, arrogant and frightening incarnation yet. Save Earth from Halley’s Comet, do battle with the alien mastermind Sil, twice, and face not just the Master – but the Rani too! Return to past adventures, battle terrible foes old and new and face the ultimate trial – the trial of a Time Lord. It’s time for a change my dear, and not a moment too soon.
