The new sourcebook focuses on the alien worlds that Team TARDIS may encounter. It offers players tools to create new alien adversaries, NPCs, and alien player characters. The book also has starship and space station creation rules as well as alien world creation rules so GMs can tailor their in-game setting to their liking. There are also background details of already existing planets in the Doctor Who universe, such as Skaro, Trenzalore, Karn, and Akhaten, found in this sourcebook.
It will retail for $39.99.
Cubicle 7 also recently released The Secrets of Scaravore, a new Doctor Who 2E adventure book (see "New 'Doctor Who 2E'").
