Delving deeper into the Arthurian lore, this week introduced the mystical sword Excalibur, which was created to defeat the Black Knight brought back from the dead by the dark sorceress Nimeuh.
As the newly appointed Crown Prince, Arthur threw down the gauntlet to avenge his fellow knights’ deaths. Yet his stubborn adherence to the Knight’s Code was in vain. For a battle of mortal combat against the Black Knight is suicidal as he cannot be killed. The Black Knight is a wraith and it can only be destroyed by magic. Thus, Merlin came up with a brilliant plan to have a sword forged in dragon’s breath in order to save Arthur. However, in a sudden fit of courage and out of love for his son, Uther usurped this cleverly-conceived plan and fought in Arthur’s place.
