Rukkhadevata was the original Dendro Archon of Sumeru and the predecessor to the current Dendro Archon, Lesser Lord Kusanali or Nahida. Like her successor, Rukkhadevata held the title of God of Wisdom and was responsible for much of Sumeru's current prosperity, creating the Aranara and Sumeru City as well as nurturing the forest they live in. In order to truly cure Irminsul, Rukkhadevata sacrificed herself by removing all memories of her existence from Teyvat.
