List of Arthdal Chronicles characters

Jang Dong-gun plays Ta-gon

Ta-gon (Jang Dong-gun) is the first son of San-ung, leader of the Arthdal Union. Blessed with both intelligence and physicality, he's a genius strategist and warrior, the head of the Daekan troops. A hero who triumphed over the Neanthals in the Great War through his war strategy. After the Great War, San-ung declared the Great Hunt, and ordered the genocide of the Neanthal. Ta-gon was in the front lines of the Great Hunt, proving his ability. Under leadership of Ta-gon, the Daekan troops not only enforced the Great Hunt, but also pacified rebelling tribes that attempted to riot against the Arthdal Union. Ta-gon's reputation in Arthdal continued to rise.

As Ta-gon became a hero for all Arthdal tribes, one person watched with wary eyes - his own father, San-ung. Although he was initially pleased with Ta-gon's cunning strategies, as Ta-gon's eminence rose, San-ung became uneasy. Overcome by power-lust, San-ung tries to take down Ta-gon by trapping him. This incites a war between father and son, and Ta-gon leaps over the mountain of his father, and takes control of Arthdal. Ta-gon finally becomes the Hero of Arthdal. Ta-gon is also Igutu (mixed blood of human and Neanthal); nobody in Arthdal is aware of that except San-ung, Eun-seom, Saya and Tae Al-ha.

Song Joong-ki plays Eun-seom and Saya, identical twins

Eun-seom and Saya (Song Joong-ki) are identical twins. Eun-seom is the son of Asa Hon and Neanthal, Ragaz. A member of the Wahan tribe of Iark, a foreigner to Arthdal. Ta-gon's most powerful enemy, in the days to come. The offspring of an alien relationship not accepted in Arthdal. Eun-seom and Saya are a mixed race of the Saram (human race) and the Neanthal, a pair of Igutus born during the Great War. An old Arthdal prophecy says that "the child born on the day when the blue comet appears will bring calamity." And so it is, on the day they were born, a bright blue streak lit across the sky. Eun-seom's mother, Asa Hon, willing to do anything to keep Eun-seom alive, escapes Arthdal and heads to Iark. But Asa Hon meets her death in the voyage to Iark.[1][2][3][4][5]

Young Eun-seom was raised in the Wahan tribe of Iark. The Wahan got used to Eun-seom's dissimilar purple lips, and the scars on his back, but Eun-seom was more unique than just his appearance. He can copy any maneuver after seeing it just once, no matter how complicated. Thus, he was teaching Tan-ya the intricate dance of the Great Spiritual Mother, that she was supposed to be mastering. In addition, Eun-seom was a better hunter than his peers, as he is extraordinarily strong and fast. Although not comparable to the Neanthal, an average man cannot keep up with an Igutu's strength and speed. Eun-seom's abilities were strange to the Wahan. Despite being raised in Wahan, Eun-seom was still an outsider. His only confidant was Tan-ya, a Wahan girl of same age whom he grew up with. To Eun-seom, Tan-ya is his family who has been there for him since he was young. Tan-ya is a thoughtful girl who always took care of the lonely Eun-seom. Eun-seom loved Tan-ya for this. Ultimately, Eun-seom's outstanding abilities and personality created a big problem, and Eun-seom is on the verge of banishment from Wahan. At the same time of Eun-seom's crisis, a danger also approaches the land of Iark. Following the orders of San-ung, the leader of the Arthdal Union, who wants to conquer Iark, Ta-gon and the Daekan troops descend the Great Black Cliff. The Wahan tribe were trounced. And thus, Tan-ya and the Wahan are taken to Arthdal. To save them, Eun-seom heads to Arthdal, the root of his secret.

Saya, on the other hand, Ragaz brought him along when he encountered Mubaek and his Saram soldiers. They fought and Ragaz died, killed by and arrow shot by Ta-gon. Ta-gon found Saya hidden in the bushes and he brought him home, giving him to Tae Al-ha to raise. Saya spent much of his life in the top most section of the Fortress of Fire. Saya's identity was revealed first time in the end of episode 6, season 1. He was shown to be manipulative and have a revenge streak, as he foiled Tae Al-ha's plan due to her part in the murder of the one he loved, Saenarae. Shortly he becomes obsessive of Tanya after meeting her and determined to keep her by his side.

Kim Ji-won plays Tan-ya

Tan-ya (Kim Ji-won) is the daughter of Yeol-son, the anointed successor of the next Great Spiritual Mother of the Wahan. The prophesied child of the blue comet. On the day that Tan-ya was born, her mother died before being able to meet her beloved daughter. Tan-ya was born on the same day as Eun-seom, the day the blue comet crossed the sky. But, the Wahan prophesy of the blue comet differed from that of the Arthdal: "The one who will break the shell will arrive on the day of the blue comet, accompanied by death. Wahan will ceased to be Wahan."

Tan-ya is a clever, pretty, bright Wahan girl, destined to be the next Great Spiritual Mother. In Iark, a land where the bow and arrow has not even been invented, she uses a sling as her hunting tool. She is a warrior capable of taking an adult's life. The Saram race cannot dream, but priestesses must be able to dream to qualify as a spiritual mother. In order to have dreams, Tan-ya is burdened with training and practice, but she has yet to meet a dream. Moreover, she has not been able to master the spiritual dance of generations of spiritual mothers. As Tan-ya becomes more frustrated and pressured, one day, Eun-seom secretly watches and learns the spiritual dance, and teaches Tan-ya. She finds out that Eun-seom has dreams, and at first, Tan-ya is suspicious. At the same time, she feels jealous. But without knowing, she begins to have feelings for Eun-seom.

The days were peaceful, until the Arthdal Daekan troops arrived in the Wahan Village. Tan-ya ends up being captured with the Wahan people, and taken to the faraway Arthdal land. Bit by bit, she feels her destiny and her anointed mission as the child of the blue comet approach her, along with the truth of the Wahan Tribe.

Kim Ok-vin plays Tae Al-ha

Tae Al-ha (Kim Ok-vin) is the daughter of the Hae Tribe Chief, Mi-hol. A scientist, warrior, and ambitious politician. The Hae people are foreigners to Arthdal who arrived from far far away, crossing the oceans. It has not been long since the Hae settled in Arthdal. The Hae chief, Mi-hol, used the exceptional technology of the Hae as a means to survive in Arthdal. As Mi-hol's daughter, Tae Al-ha realized at a young age, that if you do not become strong, you die. If you can not be a strong person, you must stand on the side of a strong person. Correct judgment about who is strong is the only thing that matters. This was carved deep into her heart. Descendants of the Hae are raised to be experts in various fields of science, and Tae Al-ha is no exception. But her interest is in power, not science. Rather than mastering the science, she would rather control the scientists. She believed that the one who could influence the people to lead the direction of history would be the person at the apex of power.[6]

With insight and analytical power that's comparable to her father, Tae Al-ha predicts early on that Arthdal is on the verge of change. Although she did not experience it, she knows from history. The explosive growth of Arthdal's agriculture and production will ultimately lead to the birth of a nation. Believing that nations are born in the midst of clashing storms and desires, Tae Al-ha finds Ta-gon. And so, Ta-gon becomes the Hero of Arthdal. Everything seemed to follow Tae Al-ha's desires and plans. She enjoys great power as Ta-gon's political comrade. Tae Al-ha had no fears, Arthdal was as good as hers. However, a strong rival appears from an unexpected place.

Although Ta-gon was older, since no one knew who Ta-gon's mother was, Dan-byeok felt no need to be vigilant against him. He does not understand why his father was hateful towards Ta-gon and guarded against him from a young age. And so, he always felt sorry for Ta-gon and had much sympathy for him.

However, Asa Ron has one thing lacking, he descends from only a branch house of the Great Mother Asa Shin, and not her direct line.

They met again during the burning of the Atturad while Asa Hon was sent there and unknowingly used as a sacrificial victim by Union leader, Sa-nung to deliver gifts that purposely caused disease outbreak in the Neanthals. In rage, Ragaz intended to kill Asa Hon in the first place but unable to do so when suddenly he fell on his knees and threw up bloods. Asa Hon then knelt and apologized to him. At that point, Ragaz noticed Asa Hon's good intention when she was holding a Neanthal baby. She also suggested that they should save the remaining children of Neanthal. As the Great Hunt was still on going, Ragaz and Asa Hon tied knot and conceived twins, Saya and Eun-seom. He was the last adult Neanthal survivor from The Great Hunt.
