What is the background of League of Legends Raven?

Hello, Raven. Backstory: In Knox Sass, as long as you have the strength, everyone has a chance to get ahead. This has nothing to do with race, gender or social status. Wen Rui is convinced of this and strives to move forward. As a soldier, she showed great potential. Although she is not tall, she mastered the use of a long sword through exercise. She is a cruel and efficient fighter, and her strength comes from her firm belief. When she rushed into the battlefield, Wen Rui's heart never wavered: she despised moral bondage and was not afraid of death. Therefore, Raven stands out from his peers and becomes the representative of the spirit of Noxas. Her extraordinary enthusiasm was appreciated by the high command, and Raven got a black rune sword, which was strengthened by the casting of Knox magic. This weapon is heavier than the ordinary light shield, which is completely in line with the raven's preference. Soon, ravens were assigned to Ionia and became part of the invasion war of Noxas.

The war soon turned into genocide. Knox's soldiers followed the war machine from Zon through the land of death. Ravens are not trained for a glorious war. She was ordered to destroy the remnants of the defeated and seriously injured enemy. With the invasion, it is obvious that this war is no longer to replace the Aiou regime, but more like destruction and slaughter. In an encounter, the raven's troops were surrounded by Ionian troops. They called for reinforcements nearby and responded to the biochemical shells of alchemist Xinji. Raven looked around, and soldiers on both sides became victims of this terrorist explosion. Raven tried his best to escape from the battlefield, but this memory could not be erased. Noxas officials have put Raven on the death list, and Raven sees an opportunity to start a new life. She shattered the rune sword, cut off the connection with the past, and wandered into exile at will. Now Raven is looking for a chance to atone and fight for the true spirit of Knoxas in his own way.
