Deep below the surface of the planet Adamantine lies a crystalline wonder world of lava seas and volcanic islands, home to living rock-people. But when the Doctor and her friends arrive they find Adamantine under threat. The seas are shrinking, the magma is cooling, and mysterious, fatal Seething Pools are spreading fast. Something has come to Adamantine - but what does it want? Fearing an invasion is underway, the Doctor must lead an expedition to the surface of the world to save its molten heart... Featuring the Thirteenth Doctor, Yasmin, Ryan and Graham, as played by Jodie Whittaker, Mandip Gill, Tosin Cole and Bradley Walsh.

For a Good Doctor there's only one rule: first do no harm. On the planet of Lobos, the Doctor halts a violent war between the native Loba and human colonists. Job done, the TARDIS crew departs - only for Ryan to discover he's left his phone behind. Again. Upon returning, the Doctor finds that the TARDIS has slipped hundreds of years into the future - and that something has gone badly wrong. The Loba are now slaves, serving human zealots who worship a godlike figure known as The Good Doctor. It's time for the Doctor to face up to the consequences of her last visit. With Lobos on the brink of catastrophe, will she be able to make things right? Featuring the Thirteenth Doctor, Yasmin, Ryan and Graham, as played by Jodie Whittaker, Mandip Gill, Tosin Cole and Bradley Walsh.
