While it draws inspiration from the classic tales, it's not a direct adaptation of any one book. Instead, it blends elements from various sources, including:
* The Mabinogion: A collection of Welsh myths and legends, including stories about King Arthur and Merlin.
* The Historia Regum Britanniae: Written by Geoffrey of Monmouth in the 12th century, this work provides one of the earliest detailed accounts of King Arthur and his court.
* Le Morte d'Arthur: Thomas Malory's 15th-century compilation of Arthurian tales, which is perhaps the most famous source.
The series also incorporates its own unique storyline and character development, adding its own twist to the classic Arthurian myth.
