When young King Arthur's sword breaks in battle, Merlin leads him to an enchanted lake. There, from waters as still as a mirror, the mysterious Lady of the Lake offers him Excalibur, the most famous sword in all of legend.

After twenty years of peace, Camelot stands at the height of its glory. But secrets are growing inside the castle, and Mordred's ambition waits quietly for its moment. So begins the slow, sorrowful fall of the fairest kingdom that ever was.

On the plain of Camlann, two armies meet for the last battle. Arthur faces Mordred, Excalibur returns to the lake, and a boat crosses the mist toward Avalon. The end of the Arthurian legends — and the promise of the once and future king.

A mysterious young man arrives at Camelot and asks only for food and shelter for a year. Working in the kitchen, he keeps a secret — and waits, patiently, for the moment to show who he really is.

On New Year's Eve, a knight who is green from head to toe rides into Camelot's hall and proposes a strange, dangerous game. Sir Gawain accepts, and discovers that honor and truth are tested when no one is watching.

At the feast of Pentecost, a golden light fills the hall of Camelot and the Holy Grail appears in a vision above the Round Table. The knights set out on the greatest quest of all, and among them rides young Sir Percival, pure of heart.

A young knight with the purest of hearts arrives at Camelot: Sir Galahad, son of Lancelot. Only he may sit in the Perilous Seat, and it falls to him, with Percival and Bors at his side, to complete the quest for the Holy Grail.

Raised by the Lady of the Lake in a kingdom beneath the waters, Lancelot arrives at Camelot as an unknown knight in white armor. This is the story of the greatest knight of the Round Table, and of what truly made him great.

From his mysterious birth to his great part in the making of Camelot, this is the story of Merlin, the greatest wizard of legend. He could see the whole of the future, yet all his wisdom could not free him from his own fate.

Arthur's half-sister, Merlin's student, keeper of the old magic. Morgana le Fay was both Camelot's ally and its enemy, and her story asks a difficult question: is anyone ever only good or only bad?

Arthur marries Guinevere and receives an enormous, perfectly round table, where there is no head seat and every place is equal. There the brotherhood of the Knights of the Round Table is born, sworn to protect the weak and defend justice.
