To bring peace, Merlin (Nicol Williamson) secures the mystical sword Excalibur from the Lady of the Lake (Hilary Joyalle) and gives it to Uther. Impressed by this symbol of power and Uther's promise of land, Cornwall relents and recognizes Uther as king. Cornwall hosts a celebration, where his wife, Igrayne (Katrine Boorman) dances. Uther cannot hide his lust and the fragile truce is broken.Uther besieges Cornwall's castle. He again asks Merlin to intervene. Merlin agrees to give him Igrayne but only if Merlin will receive the result of Uther's lust. That night, Uther's men draw Cornwall out of his castle and ambush him, killing him. Merlin transforms Uther to resemble Cornwall. Uther enters the castle, makes rough love to Igrayne and impregnates her as Cornwall breathes his last.Nine months later, Igrayne gives birth to a son. Upon seeing his son for the first time, Uther vows to become a peaceful king and secure his kingdom for his son. Merlin, who has not been seen since the night Cornwall died, appears and takes the child, as per their agreement. Igrayne is distraught and as Merlin disappears into the forest, Uther tries to stop him but is attacked by knights still loyal to Cornwall. Mortally wounded, Uther drives Excalibur into a stone, declaring no one will have the sword but him. Standing nearby, Merlin recites a spell that will keep the sword in the stone until Arthur is old enough to claim it.For the next sixteen years, no one is able to pull the sword from the stone.
