The Spring of Grief (Japanese: 嘆きの泉, Nageki no Izumi) is a landmark in Xenoblade Chronicles. It is located in Tephra Cave, by the central lake in Tephra Cavern. It is the location of the Solid Konev and a Heart-to-Heart - "Glowing in the Night" - as well as being passed through immediately before a mini-boss fight with multiple Arachno.
