Stem the Tide is a quest available in The Elder Scrolls Online. The Vestige should find the portal deep within Softloam Cavern. Dathlyn said they would need to destroy the two crystals that sustain it in order to close it.
Covenant soldiers are massing within Softloam Cavern. It won't be long before they have the numbers to launch an attack on Kragenmoor and the rest of Stonefalls.
