Cleansing The Tainted

Travel to the island to the southeast and use Elrileth's Signet Ring to cleanse and collect the tainted souls of the banshees there; then return with the souls to Guardian Elrileth. - Cleansed Tainted Soul (0/25)

Guardian Elrileth says, "They were never comrades of mine, but still the taint of the souls of the banshees on the island southeast of here should be righted. This also serves the more practical purpose of completely removing them from the island where they can threaten boats that must sail by. Travel to the island southeast of here and use my signet ring to cleanse and collect the tainted souls of the banshees there."
