The World Tree is a location in Fire Emblem Warriors.
After Darios is captured, the royal twins, Rowan and Lianna, are anxious to rescue their friend. However, outnumbered by endless forces of Outrealm Fiends and with the Shield of Flames gone, they have to look for another source of power to counter the fiends. It is when Tiki senses the sacred power coming from the summit of the World Tree. Lianna later reveals that, according to the legend, the World Tree was once where the Divine Dragon queen rested and drew her last breath due to mortal injuries after a grand battle with the Evil Dragon King, leaving behind on the top of the tree two of her sharpest fangs, the Facinna and Enliron swords.
