On Fields of Elysium in Assassin's Creed: Odyssey Fate of Atlantis, you'll encounter Marble Maiden Tributes. In Deukalion's Heritage, there are three of such tributes. Each destroyed statue will give you an ability point and experience, as well as lower Persephone's sway over the region.
Tribute next to Village of the Glorious Dead
One of the Marble Maiden Tributes can be found east from Village of the Glorious Dead. To destroy it, you need to clear the area and destroy the statue.
Tribute next to Iapetos' Ruins
The second of Marble Maiden Tributes can be found east from Iapetos' Ruins. To destroy it, you need to clear the area of enemies and destroy the statue. Remember that the tribute is located on the edge of the world, so you may encounter walls.
Tribute next to the Fortress of the Three Sisters
The third Marble Maiden Tribute is located south from the Fortress of the Three Sisters. You can find it on the top of the hill. This location offers a nice view on the waterfalls.
