THE DRAGON'S CALL
The teenaged warlock Merlin is sent by his mother to lead an anonymous life in Camelot, under the care of the court physician Gaius. On his arrival, he sees the execution of a man accused of sorcery as the King, Uther Pendragon, has banned sorcery on pain of death. A hideous old woman, the condemned man's mother and a sorceress, vows revenge ("A son for a son!") before vanishing. Merlin realizes he must keep a low profile. He then discovers the Great Dragon, who tells him that he must protect Arthur until he becomes king and guide him to unite Albion. Merlin disagrees, seeing Arthur as an obnoxious bully. At a feast, the disguised mother of the sorcerer casts a spell on the guests and attempts to stab a defenseless Arthur. Merlin interferes, saving Arthur's life, and is rewarded with a position as Arthur's manservant.
VALIANT
Uther holds an annual tournament for the knights, in which Arthur is the defending champion. Sir Valiant has a magic secret weapon: a shield from which the poisonous serpents can come to life and attack. Merlin finds out and tells Arthur. Arthur accuses Valiant of cheating, but the only 'worthy' witness has died and a servant's word is useless against a knight. Arthur is furious to be humiliated and fires Merlin. He prepares for his own match with Valiant, expecting to die. After enigmatic encouragement from the Great Dragon, Merlin decides against giving up and resorts to a magic book Gaius gave him.
THE MARK OF NIMUEH
The dark sorceress Nimueh casts a spell on a dragon egg which she throws into the castle's water supply. The next day, people start dying of a plague which turns their skin white with dark blue veins. Uther orders Arthur to search all Camelot for the sorcerer he believes to have caused the epidemic - only a magic trick saves Merlin from having his book found. When Gwen's father exhibits symptoms, Merlin disregards Gaius's warning by curing him. However, when Arthur reports the recovery, Uther believes Gwen to be the sorceress and sentences her to death. With some prompting from Morgana, Arthur goes with Merlin to hunt down the monster (an afanc).
THE POISONED CHALICE
While Camelot prepares to celebrate peace with Mercia's visiting ruler Bayard, Nimueh forges a poisoned chalice and replaces it with one due to be given to Arthur. The disguised sorceress then warns Merlin, blaming Bayard. Uther makes Merlin test the goblet by drinking from it (as he is a 'disposable' servant) and Merlin collapses. Gaius diagnoses a fatal poison; the only cure is from a flower which grows only in certain caves, but the perilous journey to it may take too long. Arthur bravely rides out, although Uther forbids him to 'risk a king' for a pawn. Nimueh plays the damsel in distress and local guide, to make sure Arthur is exposed to horrible monsters, but even on his deathbed Merlin conjures magical aid. When Arthur brings the flower, Uther jails his disobedient heir and refuses to have it brought to Gaius. Gwen's ingenuity solves that problem, but they still have to deal with Bayard.
LANCELOT
Merlin would have been killed by a griffin (half eagle, half lion) if it hadn't been for Lancelot, who attacks it and gets them away safely. Learning Lancelot's dream is to become a knight, Merlin brings him to court and magically forges proof of nobility so that he can apply. Lancelot passes hazing and close combat tests against Arthur, but is found out as commoner and jailed. When the griffin attacks Camelot, and also the royal castle, the knights' arms prove unable to harm the monster. Arthur frees Lancelot, who confronts the griffin. Merlin uses magic to help Lancelot triumph where all the other knights had failed. Uther and Arthur disagree over whether Lancelot can serve as a knight, and Lancelot leaves Camelot.
A REMEDY TO CURE ALL ILLS
Morgana falls ill with an unidentified brain disease which Gaius is unable to cure. A mysterious healer, Edwin, proves that his 'remedy to cure all ills' seemingly helps her, but actually removes the cursed black beetle that caused the illness. Uther retires Gaius and instates Edwin as the new court physician. Gaius secretly gets court archivist Geoffrey to give him access to the sealed records of Uther's purge of magic, proving Edwin's parents were executed as sorcerers. Edwin threatens to expose Merlin if Gaius tells Uther, leaving Gaius with an impossible choice. After consulting with the Great Dragon, Gaius decides to step down and leave Camelot (calling Merlin the 'son he never had'). Edwin uses another beetle to condemn Uther to an agonizing death. Gaius returns at the last minute, but it takes Merlin to save the day.

He is seeking revenge for the death of his sister, who died giving birth to Arthur by way of magic from Nimueh. Merlin learns from the Great Dragon that only a special sword (Excalibur), burnished with the Dragon's fiery breath, can kill the knight. The Dragon warns Merlin that only Arthur can wield it. Arthur is next to fight the Black Knight, but Uther takes Excalibur and faces the knight himself, slaying him in the end. Now that the sword has been wielded by someone other than Arthur, it is capable of being used for evil; to prevent that, the Great Dragon instructs Merlin to hide Excalibur far from the reach of mortal men.
THE MOMENT OF TRUTH
Hearing that his village is being threatened by a warlord and his gang, Merlin travels home with Gwen and Morgana to help. Arthur joins them and does his best to drill the peaceful villagers into a fighting force, but Merlin's friend William dismisses him as an egotist.

But when it comes to the fight, the villagers are still inexperienced and Merlin risks exposing himself as sorcerer to drive off the invaders. During the battle, Merlin conjures up a storm to drive off the invaders, which Arthur sees. During the ensuing battle, William saves Arthur's life, and takes the blame for the magic storm. Arthur pardons William on his (William's) death bed.
