Valkiri - the god of death who guides the spirits
Valkyrie, Valkyrja, Walkuere, Valkyrien, Walkyren, Walachuriun, Totenwaehlerin - literal translation should be women who choose the dead.
In Norwegian and Germanic mythology, the maids of Odin are also called "those who look for spirits". They go out on horseback with "wild hunting", or they turn into swans and fly to the battlefield to collect the fallen warriors for Valhalla Hall.
From the perspective of theology, Walkiri belongs to the goddess of fertility and destiny in the general sense of Nordic mythology. Images such as midwives, deified women, and male female patrons will appear in their dreams.
They are the gods in Germanic mythology, and they are also girl soldiers who wear shining armor and ride horses in the sky.

Valkiri undertakes the task entrusted by Odin, directly participates in the scuffle on the ground and wins over one side. The change of his appearance is a symbol of the imminent outbreak of war. Like the three Noren goddesses who weave a web of destiny for the fetus in their mother's womb, the Valkyries weave a web of destiny for war and bring them into Valhalla as guides for those heroes who died in battle. They came forward and kissed the selected candidate. Later, he introduced his dead spirit to Valhalla and was also responsible for serving the warriors gathered in Valhalla. From then on, the warriors lived happily together in an ideal way. They indulged in feasts at night and repeatedly participated in the battle in which they sacrificed their lives and became immortal. The knighthood in Northern Europe believes that women are not only men's families, but also partners in the battlefield. Valkiri is such a shield holding goddess of war. War is their favorite living environment. Their military life is full of epic tragic color.

The name Walkiri comes from Wolkenthrut and Mist. Thirteen Valkyries are listed in Ada's ballads:
"Hrist and Mist
Play the war drum for me,
Skeggjoeld and Skoegul,
Hild and Thrud,
Hloekk and Heerfessel,
Goell and Geirahoed,
Randgrid and Radgrid
And Reginleif,
Bring mead to Yingling (*). "
---------------------------------------------------The Song of Grimnet
According to the Grimm brothers, Mist in Walkiri is actually a personification of the fog.
It is said that Kara is the prophecy goddess among the Valkyries. She wore a feather coat made of swan feathers, so that he could easily skim over the enemy's head to defeat them.
Later in the Scandinavian ballad, Brunhild was mixed with Sigrdrifa, one of the Valkyries (the Giver of Victory). (The Awakening of Valkyrie in Ada's Ballads Collection is quoted)
Sigrdrifa belongs to one of those Walkiris who were originally human and were born in the royal family. She fell asleep after being cast a spell by Odin for disobeying his will (wrongly judging the victory of a battle to the party who should not win) and was demoted to earth as punishment. Later, Singer was saved and awakened. He fell in love at first sight and became a couple (omitted below, this is another story). This is exactly why Siegfried's clever plan to defeat Brunhilde in the song of Nibelungen.
(*) should be Einherjern. It refers to those lonely soldiers, the German heroes who died bravely on those glorious battlefields and were led to Varkhara by Valkiri.

In the song of Nibelungen, Brunhilde is described as a strong queen. It lives in a country called Isenstein on an island in the North Sea. Gunter, the king of Burgundy, loved Brunhilde. However, anyone who wants to win her love must compete in three events with her, and must win three battles and three victories. For this reason, he turned to the hero Qigrude for help. Qigrude agreed to him on the condition that Gonte would betroth his sister, Crimsil, to him. So both parties agreed to make a trip. Accompanied by Gonte's courtiers, Hagen and Dan Kwatt. With his invisibility cap and Ziegrud's wit, Gunter finally defeated Brunhild. So Brunhild had to marry Gunter.
However, after the feast at Worms, Gonte did not get the love of Brunhild on the wedding night, but was hung on the nail on the wall by her without hesitation until the next day. Gonte had no choice but to ask for help from Ziegrud again, and Ziegrud also quietly entered the bedroom of Gonte and Brunhild again with his invisibility cap. But this time, she used her brute force to subdue Brunhilde, and became the king's favorite. But what Qigrude regretted later was that he took away Brunhilde's belt and ring at the same time of unifying her. Later, he gave these two things to his wife, Kremschild. At that time, the belt was a symbol of virginity and should be taken down by the husband on the wedding night. Klimsild later showed these two keepsakes to Brunhill at a banquet. Brunhill mistakenly thought that his first night was not taken by Gunter, but by Ziegrud, so he suffered great humiliation, which directly led to the two queens turning over. So Brunhild instructed Gunter's courtiers to plan to kill Ziegrud.
In Didrexsaga, Ziegrud has another relationship with Brunhild. They have known each other since childhood. Mimei, the adoptive father of Ziegrud, promised to give him a horse in Brunhilde's horse farm. However, Mimei was shocked by Ziegrud's behavior. He came to Brunschild and broke into her courtyard Seegard. In spite of this, Brunsfeld received him in a friendly way, told him his royal family background and gave him the horse he had long wanted.
After Zigfried married his sister, Clemschild, he praised him and said that Brunschild was the most beautiful and intelligent girl of all. However, Brunsfeld did not accept any emotion. She was very angry about the marriage of Siegfried, as if she had a prior engagement with Siegfried. Didrexsaga did not give a clear answer here. Unlike in the song of Nibelongen, there are various disputes before the wedding. But directly into the wedding. On the wedding night, Brunhild refused her husband's love. Also in Didrexsaga, he told that Gongte was helped by Zigfried. But the specific thing is not the scuffle between Siegfried and Brunhild, but Brunhild tightly holds him in his arms. Because Brunhild loved Siegfried deeply, Siegfried suddenly showed his true shape and the two exchanged rings. Finally, Brunhilde also became the wife of Gunter, and all of them lived in harmony in Burgundy.
But gradually the relationship between Brunhild and Siegfried grew colder. As in the song of Niebelungen, there was a quarrel between Brunhilde and Klimsild. Because the latter refused to recognize Brunhild as the Queen. Their quarrel directly led to the murder of Siegfried and the demise of Burgundy.
Brenhilde in Ada is Walkiri. He was cast by Odin because he disobeyed Odin's will and affected the outcome of a war. He fell asleep on the mountaintop of Hindarfjall, surrounded by a ring of fire. Only the bravest hero, Siegfried, can break through the ring of fire and awaken it. Here, Brunhilde was born in the Wang family of Heunen and is the sister of King Atri. Heunen is the place where Burgundians found the end. She lives in a castle by the sea. After Siegfried saved her, they married and exchanged rings. But he drank the magic potion prepared by Klimsild after King Jiyuri, and lost his memory. Forgetting Brunhilde, he married Gudrun, the daughter of Klimsild. However, Brunhild did not know and was still waiting. Until he finally saw his keepsake in Gudrun's hands, he was shocked and knew that he had been cheated. Brunhilde, who learned the truth of the wedding night, was so ashamed that his servant Hagen von Tronje vowed to avenge the Lord. A new round of war against Denmark and Saxony is coming. On the eve of the war, Hagen used the excuse of better protecting Siegfried to cheat Klimsild to mark the corresponding clothes at Siegfried's vital point. The war turned into hunting in Oden Wald. Siegfried took the undisputed lead. When he finally bowed at the spring to drink, Hagen suddenly threw a death shot from behind, hitting the point. After the death of Siegfried, Hagen captured the treasure of Nibelungen and sank it to the bottom of the Rhine River. Brunhild committed suicide after seeing the dead body of Siegfried and the god horse that was buried. His body was cremated with Siegfried. Crimsild was overcome with grief and vowed to avenge his husband.
