The series is set in the shared Marvel Universe and begins with police officer Dai Thomas (a supporting character from Marvel UK's previous Captain Britain stories) entangled in a murder mystery that seems to have superhuman or supernatural involvement. Captain Britain himself is also a key character in the first arc.
As things spiral, it becomes an environmentally aware horror story, drawing on Arthurian myths to show nature - embodied by the Green Knight - pushing back against the damage done by man.
Later issues add another complication, with the destructive Red Knight and its servants, the Bane, causing havoc across the world as it feuds with its counterpart.
The first issue was published in July 1990. The series ended with issue 18, but a Sequel Series, titled simply Knights of Pendragon, was then launched as part of Marvel UK's 1992 expansion.
Tropes included in The Knights of Pendragon:
- Ascended Extra: Dai Thomas was previously a minor recurring character in the Captain Britain stories (initially in an Inspector Javert role). This series makes him one of the core cast, and he's very much the lead for the first arc.
- Fisher King: The Green Knight itself.
- Karmic Death: The fate of those who directly anger the Green Knight. A fur poacher ends up neatly packaged with his victims' pelts, for example.
- Shout-Out: When the Bane storm a London police station, one of them cheerfully sings The Pirates of Penzance song "A Policeman's Lot Is Not A Happy One" as he slaughters police officers.
- Scary Scarecrows: A disturbing turnip-headed scarecrow is a recurring figure.
- Start to Corpse: The first page of the first issue is a Splash Panel showing a dying man crashing through the window of a Tastee Burger restaurant. It's a dream sequence, but later in the issue it's also revealed to be real.
