The Kingdom of Turan decides to take advantage of Pars's moment of weakness to invade, forcing Arslan to abandon his plan to retake Ecbatana in order to secure the border at Peshawar.

Prince Arslan from the Kingdom of Pars finds himself into a predicament when a young prisoner from the nation of Lusitania holds him hostage in an attempt to escape.

Now fourteen years old, Arslan takes part in his first battle against Lusitania, and all odds seem at the Parsian army's favor, until his father, the King Andragoras III, falls victim to treason by Kharlan, one of his generals. (Source: Wikipedia)

Arslan is rescued by his loyal servant Daryun and they must run away from the Lusitanian forces, led by the General Silvermask, who ambush and capture his father personally.

Arslan and Daryun seek the help of the retired tactician Narsus, but convincing him to join their cause will not be an easy task.

While Arslan and Daryun enlist Narsus' help, Lusitania begins their siege in the royal capital of Ecbatana. Shapur is tortured by Bodin as an example for the "pagans" of Pars, but requests to be killed by one of Pars' archers. Listening to his request, he is killed by a mysterious man, who is called by queen Tahamine to be rewarded for his feat. Meanwhile, Lusitania convinces the slaves of Pars to open the city gates for them, promising to make them free men.

Gieve escapes Ecbatana after having a clash with Silvermask, who makes use of the underground tunnels to strike the palace from within, while the Lusitanian forces, assisted by the slaves, break into the capital and conquer it.

As the Lusitanian army plunders the capital, Gieve meets the beautiful priestess Farangies, who is in search for Arslan. Upon knowing that Kharlan intends to raid the nearby villages in order to capture them, Arslan and his companions decide to take the fight to the enemy.

Kharlan continues his pursuit of Arslan, unaware that he fell for Narsus' scheme and his forces are ambushed in an unfavourable terrain, where Arslan's party meets Gieve and Farangis, who join their cause as well. Meanwhile at the capital, Silvermask confronts the captive King Andragoras, revealing his identity and motives.

Daryun and Narsus infiltrate the capital in search for information, coming across Silvermask in the occasion, while Arslan has another encounter with the runaway prisoner he met years before.

Arslan and his subjects seek refuge in the Kashan Fortress, governed by Lord Hodir, but it does not take long for the party to realize Hodir's true intentions for sheltering them.

On their way to the stronghold at Peshawar, Arslan's party is pursued by a force led by Xandes, Kharlan's son who seeks to avenge his father and they are forced to split up.

Silvermask slaughters a band of thieves and when the leader's daughter is about to be killed as well, Narsus appears to rescue her. Meanwhile, the rest of Arslan's party regroups and fights Xandes' forces, including the mysterious sorcerer that aids him.

Arslan's small group is reunited at Peshawar and they begin looking at using the army there to take back the rest of Pars.

With no time to absorb Bahman's shocking revelation, Arslan must decide how to deal with the invading army led by Rajendra, Second Prince of the Kingdom of Sindhura.

Having formed an alliance with Rajendra, Arslan and company face their first hurdle in their military campaign to win Rajendra the throne of Sindhura. On their way to Sindhura's capital of Uraiyur, they must first get past the Fortress of Gujarat.

With the fall of the Fortress of Gujarat, Gadevi sets out to meet Arslan and Rajendra on the battlefield. Vastly outnumbered and facing war elephants, Arslan and company must find a way to win.

Rajendra asks Daryun to be his proxy in the duel before the gods to determine the next heir to the throne of Sindhura. Faced with the fearsome knight in black, Gadevi arrives at a terrifying solution.

With Rajendra now firmly on the throne of Sindhura, it is time for Arslan to put his affairs in order and prepare to return to Pars to deal with Lusitania.

Arslan returns to Peshawar. In the meantime, Hermes must walk the fine line between remaining useful to Lusitania and furthering his own interests.

Lords and generals from across Pars rally to Arslan. But now, Arlsan must contend with newcomers jockeying for position and the very real possibility that he will have to fight Hermes for the throne.

The newcomers continue to make trouble within Arslan's camp and they must find a way to settle these squabbles before they leave on their campaign to take back Pars.

As Arslan's army approaches the Keep of Saint Emmanuel, both sides make preparations for the crucial battle that will take place there.

The siege of the Keep of Saint Emmanuel begins in earnest and Parsian generals, who once fought on the same side, now find themselves facing each other across the battlefield.

Étoile wrestles with the knowledge that the prince, whose head he had wanted for so long, was someone he knew. And the battle for the Keep of Saint Emmanuel continues.

Arslan's army deals with the aftermath of the battle for the Keep of Saint Emmanuel.

The Turanians regroup and prepare to make another attempt to take Peshawar Fortress, this time, using more underhanded means. Meanwhile, Andragoras makes good his escape from Ecbatana and the Lusitanians.

As Hilmes continues to pursue the treasured sword Rukhnabad, he comes across someone from his past. In the meantime, in Peshawar, King Andragoras sets Arslan a task that is seemingly cruel and impossible.

Arslan and his party head for the port city of Gilan to the south and get a lay of the land as they begin their attempt to assemble an army of 50 thousand men as King Andragoras ordered.

Arslan continues his quest to raise an army of 50 thousand, as well as the capital required to fund such an army. His immediate obstacle is the suspiciously obsequious Viceroy of Gilan, Pelagius.

Back in Ecbatana, Guiscard is sorely regretting leaving Andragoras alive long enough to escape and is determined that he will not make the same mistake again.

The bulk of Arslan's people set out for an uninhabited island in search of hidden treasure, but back in Gilan, there is still the unresolved matter of the mastermind behind the pirates.

With the arrival of Étoile and Merlane, Arslan learns of the situation in Ecbatana. And while he is still far short of amassing an army of 50 thousand, he must decide whether to act upon this information or not.
