If you thought your teachers were bad, be grateful they weren’t quite as nasty as the Master. In the latest trilogy of the epic Dark Gallifrey saga, Eric Roberts stars as the evil Time Lord, who disguises himself as a tutor and takes a group of Time Lord students out on a trip. 

When their ship crashes, the young Gallifreyans find themselves trapped on a barren, twisted version of their home planet. And of course, the Master has plans for them beyond sightseeing… 

The chilling story, written by Lizzie Hopley, is split across two time periods. Years later, Gamara (Claire Huckle), a survivor of the disastrous excursion, must finally uncover the truth about what happened to her and her fellow students. 

Dark Gallifrey: Master! - Part One is now available to purchase for just £8.99 (download to own) or £10.99 (download to own + collector’s edition CD), exclusively here. Please note: the collector’s edition CD is strictly limited to 1,000 copies and will not be repressed. 

Several years ago, the Master, disguised as a tutor, took a group of Time Lord Academy students with promising futures on a field trip that went disastrously wrong.  Now in the present, they all turn up dead. 

Gamara is the last survivor – but to save herself, she will need to reveal the truth about the monstrous experiment the Master made them conduct all those years ago. 

Dark Gallifrey: Master! - Part One also features Chris Odulele, Nathan Griffiths, Lizzie Hopley, Nadia Violet Johnson, Millie Hikasa, and Francesca Gilbert. 

Eric Roberts said: “I love it because I love the Master. He is such a master! He’s so in charge and he’s so not nice. It’s always fun playing bad guys because you always get the best dialogue.” 

Producer Noga Flaishon added: “The Master is one of my favourite elements in the Doctor Who canon. I’m a big fan of characters who are the foils, the nemeses. With the Master, we have a Time Lord who is just as knowledgeable, just as clever, but where the Doctor will always seek to heal, the Master seeks to corrupt. 

“And in this story from Lizzie Hopley, we definitely see the Master as a corruptor. We have reveals and twists and turns, but at the core, it’s about six people who are being manipulated and coerced by a charismatic monster. When I first saw the story, my thought was, are we allowed to go this dark? Thankfully, I had the amazing John Dorney and Robert Valentine to assure me that yes, this is Dark Gallifrey. This is very much what we came here to do.”
