Here Be Dragons (1985) is the first of Penman's trilogy of novels about the medieval Welsh princes of
Gwynedd. Of the novel, Penman stated, “I think
Dragons is so popular because it was virgin territory for most readers. The saga of the Plantagenets was much better known, but not many people were familiar with medieval Wales or its princes. And then, too, the story of
Llewelyn the Great and
Joanna,
King John's illegitimate daughter, is a remarkable one, which struck an emotional chord with many readers.” Penman's characterization of
Simon de Montfort is that of a man increasingly disillusioned by his sovereign, who rebels in 1263, becomes regent to Henry III, and attempts to re-establish rights granted under the
Magna Carta. In addition to the story of Simon de Montfort and his wife, Eleanor the Countess of Pembroke and sister to King Henry III, the novel presents characters such as the Welsh ruler Llywelyn Fawr and London's FitzThomas. Of her research for
Falls the Shadow, Penman explained: "I did a great deal of on-site research, visiting the castles and battlefields that figured in Falls the Shadow, visiting the Reading Room at the
British Library, the
National Library of Wales in
Aberystwyth, and local reference libraries… Here at home, I made use of the
University of Pennsylvania Library in Philadelphia, which has an excellent medieval selection. But it really helped to see the scenes for myself. At Lewes, we actually walked along the same path that Simon de Montfort and his men would have followed. It was breathtaking to stand on the Downs, gazing out upon the same view that he would have seen". The conflict between the Welsh prince
Llewelyn ap Gruffydd who is the grandson of
Llewelyn the Great of
Here Be Dragons, and England's King Henry III is one subplot. Additionally, Penman chronicles the life and character of Ellen, daughter of Simon de Montfort and niece to Henry III; her betrothal to Llewelyn (negotiated prior to de Montfort's death); and the conflict between Ellen and her cousin Edward, soon to become
King Edward, who opposes the betrothal. == Plantagenet series ==
