Dylan has seized Greystone, prompting King Arthur to send an army to reclaim this castle for the side of good. The king allows Valiant to take part in the campaign despite his fear that the prince won't be able to keep his hatred in check. It turns out that Arthur should be more worried about Sir Gawain, who is concealing a serious injury in order to stay in command of Camelot's army. How can Dylan be defeated if Gawain lacks the strength to lead?

Sir Gawain can hardly contain his boredom as he leads a small battalion to the Roman Wall on what he believes to be a wild goose chase. Julian the gatekeeper is such a simple-minded buffoon that his warnings hold little value to the proud knight. But trouble is in fact brewing up north, suggesting that there may actually be an impending threat to Camelot's safety. Valiant and Arn must uncover the problem on their own when Gawain can't be located by any of the men.

The day has finally come to deliver Baron Draconarius to King Ian so that he can be punished for the murder of Kengary's chief advisor. This is a dangerous time to do so, for the kingdom of Kengary is in the middle of a bloody civil war caused by the as-yet unavenged crime. Valiant is assigned the task of escorting the prisoner to his fate (which is sure to be death). Unfortunately, his hate-fueled drive to see that his old foe pays for his crimes places the entire mission in jeopardy.

Lord Maldon and his follower Allen have stepped up their efforts to generate civil unrest between foreigners and native Camelotians. One of their schemes forces Valiant to return to Camelot for the sake of an injured loved one. Once home, he learns that King Arthur intends on taking advantage of the upcoming Sword and the Stone Celebration to set in motion a plan to help combat Mordred's forces. What shocks the prince, the queen, and the other Knights of the Round Table about this plan is that their king must die for it to succeed.

Mordred's army is only two days from the castle and outnumbers Camelot's forces three to one. This leaves Valiant with the dual tasks of fortifying his soldiers for a bloody battle and convincing the fleeing populace that all hope did not die with Arthur. The surprise reappearance of Lady Morgana does little to ease our hero's troubled state of mind. Especially after she hands him solid proof identifying the knight who is even now plotting to cripple the command structure of Camelot's army.

Dreams of trouble in Bridgeford prompt Rowanne to return home and check on her father and mother. She leaves with Arn against Valiant's protests that she is just homesick - the two of them are captured by Duncan's men just outside the town's borders. The young warriors are sentenced to the same fate as the other townsfolk who have lately spoken of Camelot against the baron's wishes. What can Valiant do to save his friends and liberate Bridgeford from this tyranny?

Dragons are being blamed for a series of devastating attacks that are obliterating Camelot's fortresses. Sir Bryant and the trio visit the estate of Lord Maldon to see what he knows, but the son of one of Arthur's old enemies refuses to treat the threat seriously. Furthermore, there is a secret project going on deep in Maldon's bell factory that the group suspects could mean trouble. Valiant's attempt to secretly spy on their host leads to a revelation that could spell the end for Camelot.

Valiant is directly advised against returning to Camelot via a dangerous route through the Great Swamp. But the prince is far too curious about the ""great evil"" that lives there to pass up the chance to investigate. Arn and Rowanne soon wish he had heeded the warning as they are all attacked by creatures out of a nightmare. In fact, that's just where they've landed themselves - in a nightmare world that is controlled by an old enemy.

Princess Aleta and King Hugo's visit to Camelot shortly precedes Sir Mordred's triumphant return from King Olaf's court. Lord Maldon has also arrived to continue stirring up trouble between native Camelotians and their foreign neighbors. Tensions mount between Arthur and Mordred over their long-held philosophical differences and Hugo and Valiant over Aleta's future. In such a heated environment, one spark is all that's needed to send everyone spiraling out in different directions - all for Mordred's benefit.

Prince Valiant and his army land at Thule and lay siege to the castle with the help of the local peasants. Our heroes have an extra card to play when Dylan is taken hostage during a skirmish. The prince relies on Merlin, Arn, and Rowanne to oversee his design to tunnel underneath the castle and cut off its water supply. But this plan could be ruined when King Willam gets captured by Sinnin while trying to do things his own way.

Sir Mordred's triumphant return after laying siege to the Vikings is bittersweet for our heroes. While they are awestruck to see the king's champion and dear friend in person, they are saddened by the knowledge that this latest battle with the Vikings could have been avoided. Valiant, Arn, and Rowanne are more determined than ever to discover the identity of the traitor within Camelot's walls. This search for the truth brings the prince to the attention of two powerful new enemies who need him silenced to further their own agendas.

The suspicious behavior of Sir Gideon, a legendary Knight of the Round Table whose hand was cut off by the Bronze Knight, arouses the attention of Sir Giles. The young knight enlists Valiant's help in investigating the matter; this leads to the discovery of an extortion scheme taking place at the Twilingham silver mine. Although Valiant wonders if Giles's feelings for Gideon's betrothed are clouding his judgement, he still encourages his friend to bring his accusation to the king. Yet Giles's fear of losing his standing as a new knight could very well prevent the truth from coming out.

Arn feels unworthy of knighthood in the presence of the noble-born knights who have come to compete in Camelot's tournament. But he finds renewed confidence through his new friendship with Sir Harold of York. Harold, a knight who boasts of surviving the legendary Combat of the Thirty, inspires Arn by revealing his own peasant ancestry. But Arn's newfound elation may be deflated when Rowanne explains her unsettling suspicions about Sir Harold.

King Ian of Kengary has been killed in the middle of his campaign against the McGrath clan. Duncan Draconarius - Ian's trusted friend and advisor - cannot hope to continue the war and avenge his king's death until the subject of Ian's succession is settled. A peace delegation led by Sir Valiant is sent to Kengary to help straighten up the mess and determine whether Camelot should send military aid to its ally. Unfortunately, all is not solved even when a new ruler is abuptly decided upon.

Rowanne is kidnapped by John Brodige, an inept buffoon out to claim the reward Baron Draconarius has offered for her. It seems the young woman has broken the law by leaving home without the baron's consent. The pair are pursued by Valiant and Arn, who don't know that Brodige poses little threat to their friend. The real threat comes from Garth, the baron's ruthless bounty hunter, who will kill any man who comes between him and his prize.

After weeks of searching with no luck, the trio begins to doubt the truth of Valiant's dream of Camelot. But the appearance of a wounded falcon within the Castle Keep leads to an omen that renews faith in the mission. The falcon repays Valiant, Arn, and Rowanne for tending its injuries by leading them straight to Camelot the next morning. Unfortunately, our heroes do not receive the welcome that they were anticipating.

With Arthur and Guinevere gone, Lady Morgana seizes an opportunity to rid herself of long-time rival Merlin once and for all. She poisons the old wizard with a sleeping potion that traps him in a dream world that she controls. The trio only has a day to save him and seeks help from an eccentric alchemist named ""The Mighty Oom."" Rowanne tests the antidote he gives them and falls seriously ill, which forces her two friends to confront their feelings for her.

A young waif named Dennis falls uder Valiant's protection after being abused by a thieving juggler called Kerwood. The duo become fast friends when the friendly and eager boy reveals that he too has dreamed of Camelot long before he knew it existed. Together they fight for Dennis's right to remain in Camelot despite Kerwood's legal claim to him. Yet Dennis's explanation of where he comes from could forever drive a wedge between him and the Prince of Thule.

The body of Dylan, elder son of the exiled Sinnin, is brought to Camelot by a man who swears he saw Valiant commit the murder. On the corpse is a message from Sinnin asking his other son Dennis to come back to the family and make a fresh start. King Arthur, Merlin, and Dennis all have their doubts about the picture that is being presented before them. Yet with Dylan's lifeless body right there and Valiant not present to deny the charges, what other explanation can there be?

The two would-be knights run afoul of Sheriff Robert when they stop him from abducting Rowanne (the blacksmith's daughter). Their stay at her home that evening reveals that she is far from a typical maiden in distress: the young woman has spirit and a deadly aim with a bow and arrow. The visit takes a near fatal turn when Robert comes to exact revenge for his humiliating defeat. Valiant and Arn also have to contend with Robert's powerful brother Duncan when word of their quest reaches him.

Rolf, Valiant's old mentor, has come to Camelot both to deliver a letter from King Willam and spend some time with his beloved pupil. But the prince is too angry to read what his father has to say and too busy training with Sir Bryant and Sir Gawain to make time for his friend. Arn provides some measure of comfort for Rolf but cannot displace his yearning to reconnect with the young man he has loved like a son. Valiant must learn the hard way that he should take advantage of his friend's presence while he can.

Proud bachelor Sir Gawain is about to marry Queen Ilene of Perilous Garde, and our heroes are Camelot's emissaries to his nuptuals. The perfection of this extraordinary mountain city is sharply contrasted with the devastation of the drought-ridden village in the valley. Valiant, Arn, and Rowanne are sorely tempted to take up Queen Ilene's offer to stay in this small paradise after experiencing its comforts and beauty. But all this changes when Arn learns from one of the villagers about the secret behind Perilous Garde's prosperity.

After helping the eager young Sir Dylan gain admittance to Camelot's gala, Valiant is crushed when Merlin orders him to spend this holiday fixing carriages. His interest in his chore is temporarily aroused upon learning that one of the older carriages once carried King Arthur on his first important peace mission. Just when he is starting to fix that carriage's wheel, Sir Dylan gives him a chance to attend the gala as his guest. The prince makes shoddy repairs on the worn out wheel without realizing that he may not be able to go back and properly finish the job.

Our heroes journey back to the marsh in order to enlist King Willam to join in the fight for Thule. On their way, they are ambushed by a bullying brute named Vladimir who has been plundering the countryside with his band of thugs. Valiant orchestrates their escape and the entire group finds refuge in Arn's hometown. Upon learning that his old friends are living in a constant state of fear, Arn wonders if he should permanently stay behind and help them defend their homes against Vladimir.

Believing that Sir Valiant has an innate understanding of justice, King Arthur appoints him to the distinguished post of Sheriff of Hammerscape. An honored Valiant takes Arn and Rowanne with him to the town to begin his duties. It's not long, though, before he learns how difficult it is to uphold both the letter of the law and the cause of justice. This dilemma comes to a head when Sir Bryant is accused of high treason by the town's mayor.
