Overview
Buer also known as the God of Wisdom and Lesser Lord Kusanali, is the current Dendro Archon among The Seven who presides over Sumeru and the new incarnation of the previous Dendro Archon, Greater Lord Rukkhadevata. She currently resides in her vessel as Nahida.
She is the youngest and likely the newest among The Seven, having risen to this position following the death of Greater Lord Rukkhadevata during the cataclysm five hundred years ago.
Soon after her birth, the sages of Sumeru took her to the Sanctuary of Surasthana, where her physical self remained, never interacting with the world. However, she watched over Sumeru through the Akasha Terminal, which she was linked to.
Due to the sacrifice made by Greater Lord Rukkhadevata, which caused all memories of her to disappear from Teyvat, Lesser Lord Kusanali is believed by all, including herself, to have always been the original Dendro Archon, and that she simply lost all of her memories and knowledge during the Cataclysm, resulting in her imprisonment by the sages. The only known person to remember the true story is the Traveler. However, Kusanali seems to subconsciously know that there is more to the story than she can remember, yet does not wish to investigate the topic.
