So the thing is a new show, called Dragon Slayer - https://www.warwick-castle.com/dragon-slayer/
The show incorporates fire jousts, battles, stunts, horse processions, fire, projection mapping and more. It's set around the mythical, and "forgotten", story of the Guy of Warwick.
The shows take place on selected dates in August, ticketed as a separate event, and is 90 minutes long! Special food will be available too.
Prices start from £15, with the standard 20% discount available for Annual Passholders. Perhaps a tad expensive, but I reckon it could be something pretty special.
