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?

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?

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.

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.

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.

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.

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.

A convocation of the world's greatest scholars is being held in Camelot under Merlin's direction. The wizard's pleasure at the wonderful turnout turns to fear when he spots a face from a past event he has long kept hidden from Arthur. His terror at being exposed causes him to shun virtually everyone at the celebration, including his old friend The Mighty Oom. But a series of mysterious accidents may force Merlin to confess his greatest shame to preserve the safey of those he loves.

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.

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.

On the day that Ian, Warrior King of Kengary, comes to Camelot to negotiate an alliance with Arthur, Baron Draconarius and his brother Robert arrive to seek aid from Arthur. Arthur barely restrains his deep-rooted hatred for Duncan as Guinevere offers him food and shelter for the night. Duncan repays this kindness by plotting to sabatoge the negotiations with Kengary. Soon the king's faith in his New Order is put to the test when the baron's actions go too far and Ian demands justice by the sword.

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.

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.

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.

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.

An ordinary mission brings Valiant into contact with an old friend he has not seen since Thule was first conquered. Lorne, an old teacher of the prince's, has been using his expertise as a strategist to train peasants to defend their homes from danger. Valiant offers the former Man-at-Arms a chance to once again plan and fight for a royal cause by returning with him to Camelot. But is Lorne still up to the challenge of entering into combat amongst seasoned warriors?

Sir Lymond sends word to Arthur that the northern Venicone tribe has finally agreed to negotiate a trade agreement with Camelot. Sir Gawain and the trio are then sent north to help Lymond prepare for the king and queen's arrival. While there, our heroes begin to suspect that the Venicones actually have hostile intentions. Some undercover spying in the Venicone camp is required in order to gather enough evidence to warn Arthur of the danger he may be in.

The entire town of Harmony is up in arms against the neigboring town of Perkshire. The dispute centers on the fate of Adam's Oak, a beautiful and historically significant tree that is in danger of being torn down to make room for a bridge. Prince Valiant must settle the dispute but soon learns that both sides have convicing arguments in their favor. Valiant's eventual decision leads to a surprise stand-off against an old friend who tells him to change his mind or fight to the death.

The battle with Mordred's forces is fast approaching and things do not look good for our heroes. Aleta and her army could offer Camelot the support it currently lacks from its people, but only if Lord Maldon does not act on his suspicions of the Queen of the Misty Isles. Meanwhile, Allen returns to the Chapel of the Sword and the Stone and uncovers far more than he was sent to find. Could his discovery save the New Order from oblivion, or are Valiant, Arn, Rowanne, and their army doomed to be crushed by Mordred's superior numbers?

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.
