Martin R.R. George, a Westerosi author, decides to write a fantasy book series on his kingdom of England.
He creates the history of his kingdom, divides it into political entities, has some warring factions, builds up a culture for his various peoples, and writes character backgrounds. He shows us that historical events can be re-imagined for a fantasy fiction series, and draws inspiration from historical conflicts like the War of the Roses.

George goes into great detail about his various lands and cultures. The northern people of Albion are rough, proud of their warrior spirit, and
He employs the help of a few friends and starts writing, but everything comes to a halt when the political landscape of England changes in 1485. George must adapt his stories to fit the new regime, leading to tense discussions on the changing of the narrative to keep it historically accurate.

Directed by Marc Munden, "The Serpent's Sire" is an imaginative and intriguing exploration of the intersection of historical fact and fiction, as well
