Winter came to South Oxfordshire on Saturday as white walkers roamed the corridors of Abingdon and Witney College.
The inaugural Thames Con featured fantasy fans dressed as their favourite heroes and villains from TV and film, including blockbuster series Game of Thrones.
Stormtroopers, Batman and even Pennywise the Clown from Stephen King’s IT could be found wandering the campus surrounded by stalls selling memorabilia and artwork.
Actors from Game of Thrones held a Q&A, while Robert Llewellyn and Danny John-Jules revealed there will be a 13th series of sci-fi sitcom Red Dwarf.
Headliner Sir Tony Robinson reunited the cast of his BBC comedy series Maid Marian and Her Merry Men for the first time in more than 25 years.
Adam Morris, who played Robin Hood in the children’s show, said: “I haven’t seen the rest of the gang really since the mid nineties.
“This weekend is not only great for the fans to meet us in person, it was also a chance for us to catch up with old friends and reminisce about those muddy days back at the hideout in Sherwood Forest.”
Creative director Sarah Williamson said: “We are thrilled with how the first Thames Con event has gone, and are bowled over by all the amazing feedback we’re getting from those who came.”
