I would like to share with you a historical epic about  the story of one  Great King of Goguryeo (ancient Korea).  He was the 19th King of Goguryeo. This historical epic  interleaved  with  fantasies was made into  a mini Korean  TV series , called  THE LEGEND. Its kind of challenging to relate the whole story based on  the TV drama series which  had 32 episodes. But I shall try.
The central figure in this TV drama was of course the would be King of Goguryeo, Dam-deuk. SUJINI was the heart warming character that added a flavour to the drama.
The original Korean title to this drama  is actually  "Tae Wang Sa Shin Gi. " Tae Wang "  here means The Great King  and  " Sa Shin " means Four Gods or to be precise Four Guardians. Sa Shin are mythical creatures that possessed supernatural powers. They were  however not deities but servants of god heaven. These mythical creatures  were brought down from heaven to serve the first  King of ancient Korea.
Hence the original title literally  means The Story of the Great King and the Four Gods also The Story of the First  King's  Four Gods. 
This  Korean TV drama  series unfolded with Sujini as a young orphan girl who lived in a village called Geomul. Hyeon Go a village elder looked after her  and considered her his disciple. Sujini had led a hard live  and since she lived among men in the village she developed a boyish traits. 
When Hyeon Go was  appointed  as the new clan leader in the village, he was given the task to look for the new King of Goguryeo. He , therefore,  set out with Sujini on  a journey to a village in Goguryeo  where the Star from Heavens was  sighted 10  years ago. During the journey to this village in Goguryeo,  Sujini  wanted to know about the legend of the First King's Four Gods.
Hyeon Go  then related to her about how Hwanung who came down from Heavens to make the world a better place.
According to Hyeon Go, the legend happened many centuries ago. The Tiger and the Bear tribes were fighting with  each other endlessly.  Due to this endless unrest Hwanung from Heavens wanted to help the earth people.
When Hwanung came down to earth he brought with him  the three Gods of nature, Baek-Ho  ( the White Tiger),  Cheong-Ryong ( the Blue Dragon) and Hyeon-Mu ( the black Turtle -Snake). He befriended the Bear tribe and made a young brave woman, called Sae-oh to be their leader. Meanwhile the Tiger tribe had a new  leader called Kajin. She was given the fire power when the old Fire Priestess died. 
One day, Hwanung helped Kajin to heal her wound when she was wounded  in a fight.  Kajin soon grew to love Hwanung but her love was not reciprocated because Hwanung had already  fell in love with Sae-oh.Their love gave birth to a son. When Kajin learnt about this she was raged with jealousy and turned her tribe against Hwanung. In the fight that ensued  she stole Sae-oh's son. Tragedy struck when Kajin threw the baby down the cliff  and this had made Sae-oh became angry and lost control.
Earlier to this, Hwanung had  managed to take away Kajin's fire power and sealed it in a stone. Hwanung then gave this stone to Sae-oh. She wore it as a pendant around her neck.  Sae-oh was also taught how to control the fire power.  
When Sae-oh in a rage of anger, causing her to lose control, the stone  turned into a Dark Joo-jak or the Black Phoenix. All hell broke loose. It  was destroying everything in its path. Nothing could defeat the Dark Joo-jak. Finally, Hwanung shot the Joo-jak with the Heavenly Bow before it could further destroy the earth . The tragedy ended when Joo-jak was killed and so did Sae-oh. Kajin too died when she jumped off from the cliff.  Hwanung, however,  managed to save his son. The stone became the fourth Symbol /Guardian -  the Phoenix or Joo-jak.
When earth was back to normal ,  Hwanung returned  to Heavens. He  left behind his son with  the Three Gods/Guardians  of nature and the stone that sealed with Fire Power that would turned into its real  form, the Phoenix or Joo-jak.  While on earth these Four Guardians  took the form as non-living Symbols. Hwanung's  son was named  Tangun. This was how the Tangun legend started or The Story of the First King's Four Gods.
One night , many centuries later,  villagers  from Goguryeo saw a Heavens Star lighted up in the sky . This was the Joseon Star.  According to  their belief, when this  Star appeared,  a new King was born to rule the Kingdom of Goguryeo. At the same time the Four Symbols or Four  Gods would came to life. However, there were two births that took place on  that historical night.
In Hyeon Go's search  to look for the new King, he took with him one of the Four Symbols that was being guarded by his previous leader.  This symbol was the Turtle-like Snake called Hyeon- mu. It was said that  this symbol would took its real form when the true King of Goguryeo was found. In order for this  person to be a Great King he needed these Four Symbols. 
As accounted in the legend, the Four Symbols that were left behind by Hwanung were being kept  secretly by their respective guardians.  So Hyeon Go went on a quest to look for the new King and  the guardians of the other three symbols, i.e Cheong-ryong ( Blue Dragon), Baek-ho ( White Tiger) and  Joo-jak ( Phoenix) with Sujini tagging along. However, Hyeon Go from Geomul  was not the only  clan leader who was interested in looking for the new King and the other three Symbols. Another evil clan , the Hwangcheon and its leader Daejangro was the other interested party. Daejangro wanted the Four Symbols all to himself to make him young again and to live for eternity. 
While in search for this new King, Sujini had picked up some bad traits in the village at Goguryeo.  She began to love money, wine and gambling. Though as a young girl she was always into mischiefs, she grew up to be a saviour to Dam-deuk,  the would be King of Goguryeo, when he befriended her. Sujini soon turned into a sensitive and selfless person when she began to fall for Dam-deuk.
Legend has it that the soul of Hwanung was reborn in Dam-deuk.  When Dam-deuk  was a young boy, he befriended a girl from the village temple  who was undergoing a training to  become a priestess. The girl was Kiha, who happened to be Kajin reincarnate. She became Dam-deok's confidante and eventually his true love. 
Sujini was of course Sae-oh reincarnate. Her life got accidently entangled with Dam-deuk. When Dam-deuk first befriended her she did not know his true identity.  They became close and without realising it , she fell in love with him. She played a central role in Dam-deuk's  life  when he was still the Crown Prince. When Dam-deuk became the King she fought many battles alongside him. 
The plot in the drama thickened when there was also another contender to this King title and he was Dam-deuk's cousin, Hogae. The main villain in this story  was Daejangro, leader of the Hwancheon clan. This clan had the attributes of the Tiger Tribe and  obviously its leader had dark powers. Daejangro's intention  was to help Hogae's family so that  Hogae would be made the King and he in turned obtained the eternal powers of the Four Symbols. 
On the night  the Joseon Star appeared , Daejangro's men went on a rampage to look for the Four Symbols.   When they  raided Kiha's  house, they  killed her parents and took Kiha with them when they saw a stone pendant  - the Phoenix Symbol  was on her. Unbeknownst to the men,  Kiha's parents had her baby sister, hidden in a bean pot under the house. After the raid , men  from the Geomul village who had the same intention of looking for the other three of the Four Symbols  came in pursuit and found only  a baby hidden under the floors of Kiha's parents' house.
Now that the Phoenix Symbol was in the hands of  Daejangro he quickly used its power to tranform him to look younger. As Kiha was still a child when she was kidnapped by Daejangro's men  it was easy for him to control Kiha's mind. As a result when she grew up  she  completely forgot about her baby sister. 
On the other hand,  Kiha's baby sister  was found and saved by the Geomul clan. When they  found the baby they saw the Dark Joo-jak mark on her.  They believed that  when the baby  grew older and whenever she became angry and lost control  she would turned into the Dark Joo-jak. The Geomul men then decided to give the baby's name  SUJINI, meaning the mistress of the Dark Phoenix.
Incidentally, before the old leader of the Geomul clan died, he had instructed Hyeon Go  to  kill Sujini if this myth turned true. Hence Hyeon Go's duty was to take care of Sujini and kill her if she happened to  turn into the Dark Joo-jak or Black Phoenix.
The road to kingship for Dam-deuk was full of obstacles and grief. When Dam-deuk's uncle, the reigning King died, his father became the next  King. As a result he  was made the Crown Prince  at the age of 11. After his father died, Dam-deuk was made the King at the age of 17. But he had to fight his  enemies within and outside the Palace.
As a young boy, Dam-deuk admired his cousin, Hogae who was courageous and skilled at martial arts. They became good friends. However, Hogae  turned against  Dam-deuk when he belived the Crown Prince  killed his mother. Hogae wanted to relive  his mother's dream to make him the King. In the meantime Hogae too  developed feelings for Kiha.
While Dam-deuk  was still the Crown Prince he used to creep out of  the Palace and went into the village.  It was during these secret outings, that he met Sujini in the village.  When Sujini later developed  feelings for Dam-deuk, she kept  it  to herself.  She knew that Dam-deuk had only eyes for Kiha.
In one  life threatening incident, where Hogae and his men wanted to kill Dam-deuk , Kiha managed to salvage him and brought him to the edge of the village to hide. On that night, they slept together for the first time. Unknowingly  to Dam-deok, on that night, Kiha bore him a son.
The next morning, Dam-deuk found  Kiha's note  that she's going back for help. Instead, he found himself  being attacked by a group of men. He managed to escape from his attackers and  left  his village with  the help of Sujini , Hyeon Go and some of his loyal friends.  However, while on the way, Dam-deok and  his other followers were cut off from Hyeon Go and Sujini. They were being cornered by Hogae and his men. To avoid bloodshed, Dam-deuk surrended to Hogae but Hogae  shot him with his arrow. At that instant the Turtle-like  Snake  Symbol in Hyeon Go's hand  somewhat came to life and helped to  protect Dam-deuk and those who were trapped with him. When the Turtle-like Snake  Symbol came to life it emitted a strong bright light which blinded their enemies. They then stopped attacking Dam-deok and his men and  fled from the scene. On witnessing this magical incident Hyeon Go realised that Dam-deuk was the true King  of Goguryeo. 
Dam-deuk and his followers managed to reach the Geomul village safely. When Dam-deuk  had recovered from his wounds, Hyeon Go told him he was the true King of Goguryeo. He could not accept what he heard.  All he ever wanted was to run away with Kiha and lived a life together. While at the Geomul village he  received another shocking news that  his father had been killed. He was grief stricken when he was told  that Kiha was responsible for his father's death. Hence started the friction between him and Kiha. Daejangro's plan to make Kiha looked  like the enemy was slowly working. Dam-deuk began to believe that Kiha was the enemy.  When Dam-deuk totally rejected Kiha, she sought solace in Hogae though her love still remained for Dam-deuk. Unknown to Daejangro, Kiha had her own selfish dream that to be the Chief Priestess to the Palace. She knew from Daejangro that she was the Phoenix Mistress and had mystical powers. She used Hogae to achieve her plan. 
When it was time for Kiha to deliver her baby, Saryang, Kiha's loyal guardian and Daejangro's right hand man, sought the help of Sujini. Saryang then explained to Sujini that Kiha was her elder sister whom he had kidnapped the night when the Joseon Star appeared. Saryang also told Sujini that Daejangro wanted the blood from the baby's heart for his selfish needs. Daejangro believed that the blood  from the heart of Kiha's baby (the bloodline of the Goguryeo King) would gave him eternal life. When Sujini heard this , she could not but helped her sister and her baby. Saryang and Sujini agreed to tell Kiha  that her child died on giving birth. Saryang then  fooled  Daejangro that Kiha's baby had been killed and gave another child's heart to him. Daejangro, however, was furious when he discovered  later that Saryang had betrayed him and instantly killed him.
When Dam-deuk had became King, he still befriended Sujini.  On knowing  that she would turned into the Dark Joo-jak,  Sujini made up her mind to leave the Palace and the King. The idea suited her  as  she had also agreed with Saryang to keep Kiha's baby safe from Daejangro.  She  left  the village with Kiha's son and went into hiding.
Many years passed and Dam-deuk had reached his peak as the King of Goguryeo. He was known as Gwang Gae Toh Dae Wang. Gwang Gae Toh means broad expander territory. He had made himself the Great King of Goguryeo. But he still felt lonely without Sujini. He wanted her back in his life. When the  King finally managed to track down Sujini , he found her with a small boy. He did not know it at the time that this young boy was his child with Kiha.
The epic ended with  the confrontation of Daejangro, Kiha, her son, Sujini , and the King of Goguryeo. Kiha had earlier learnt  from Sujini that her baby did not die that night and that Daejangro had kidnapped him.  Kiha was still under Daejangro's spell and was not able to fight him off. She was being mind-controlled by Daejangro  to kill her own son. Sujini who witnessed  the life threatening incident was not able  to stop her.
Finally when the King arrived at the scene, he managed to set Kiha free from Daejangro's control by killing Daejangro with the Heavenly Bow.  Unfortunately, the King was too late to save Kiha who by then had turned into the Red Phoenix. He regretted that he did not believe Kiha's  words when she tried to tell him the truth.
The King , on  realising that the power of  Heavens  should not interfere  with  the lives of the people on earth, broke the Heavenly Bow.
So ended the lives of the guardians of the other three Symbols or Gods  of the Great King of Goguryeo.....
