Blodeuwedd, wife of Lleu Llaw Gyffes: Cantre'r Gwaelod. Cantre'r Gwaelod, legendary ancient sunken kingdom: Although not as famous as Atlantis, with which it has been compared by some modern authors, Cantre'r Gwaelod has featured in fiction with a Welsh flavour, notably the alternate universe  Louie Knight series. In the satirical parody "Aberystwyth Mon Amour", a group of Druids plan to launch an ark and reclaim the land of Cantre'r Gwaelod. Cantre'r Gwaelod is also a major location in Susan Cooper's "Silver On The Tree", the fifth and final book in her series "The Dark is Rising".

Gwydion, magician, hero and trickster: Lloyd Alexander's "Chronicles of Prydain", a series of fantasy novels inspired by Welsh myths, has a character named Gwydion, based somewhat on the Gwydion of myth, but markedly different in terms of moral character. The character is not included in the Disney animated film based on the novels. Patricia Kennealy-Morrison's "Keltiad" series - Irish, Welsh and Scottish legends translated to an interstellar, "Star Wars" style  context — has a character named Gwydion Prince of Don as its co-protagonist. Like Alexander, Kennealy-Morrison bases her character on the mythological Gwydion, but humanizes him through her own creative process. He also appears in Phillip Mann's alternate history series "A Land Fit for Heroes". Judith Tarr's fantasy series, "The Hound and the Falcon" and the "Alamut" series, features Gwydion as the immortal elf king of Rhiyana, a side character in both series. Robert Carter's "The Language of Stones" series, has a short appearance in "American Gods" by Neil Gaiman and is the ancestor to the  main character in Jenny Nimmo's "Snow Spider Trilogy". In "The Mists of Avalon", Gwydion is the birth name of both King Arthur and Mordred. The name Gwydion also appears in the Sierra game "King's Quest III", where a Prince Alexander of Daventry has been kidnapped by an evil wizard named Manannan who renames him Gwydion. Gwydion is also one of the main protagonists in the books of the Welsh author Jenny Sullivan. Llŷr. Llŷr originally a deity, father of "Manannán mac Lir": Lloyd Alexander's "Chronicles of Prydain" includes a "House of Llŷr", a royal family whose female  members are often enchantresses.
