Ruquinjé

"'Ruquinjé...?' It was a word he’d never heard before. Li Gan sketched the characters it was written with on the table with his fingertip. Six, meaning six people? Leaning, and princesses. Toppling princesses."

- Log Horizon 4: Game's End, Part 1

The Ruquinjé (六傾姫, lit. Six Toppling Princesses; read as ルークインジェ), also translated as Luquenje, were six princesses of the Alv born in different parts of the world. Despite each of them acting individually, they were the masterminds behind the long terrible war between humans, dwarves, and elves to avenge for their people's destruction 350 years ago, which happened before the first World Fraction where they were supposedly killed. Some led the remaining Alvs while others manipulated kings and emperors. When they finally were pushed to the edge of defeat, the six princesses caused the First World Fraction and the rise of the demi-human races as a final revenge using unknown Alv technology and science.

One of the Ruquinjé, known as Tokinagi, was reincarnated as the Lander girl Nagi. The Half-Alv Village of Oenotheran worship her and await the day that she will return, destroy their oppressors, and create a paradise for Half-Alvs. However, she currently has no intentions of taking revenge for her previous defeat, and her animosity towards humans is slowly ebbing away. Roe2 has a Summon, Sword Princess: Al Quinje, that seems to be an incarnation of one of the Ruquinjé.

Trivia

 * In the Guild Hall meeting room that was used for the Round Table Conference, the statues of the women overlooking the room are the Ruquinjé. It is unclear whether they were actually all identical, or if the appearances for all six were based off of one that actually lived near the region.
 * One of the popular translations for the kanji of their name is "Six Scrapped Princesses," but "Six Toppling Princesses" is more accurate.
 * The pronunciation for Ruquinjé stems from the the Chinese pronunciation of 六傾姫, which is "liù qīng zhěn." Similarly, much of the Spirit Theory follows terminology and concepts that originated in China, such as yin-yang and qi. Roe2's Al Quinje has its name based on similar roots, but instead of six (liù), the number is two (er).
