It takes its namesake from the Lett River, which allows the lands around it to be fertile despite the nearby wildlands, but has the downside of the occurrence of extremely dangerous floods. As a result, Clavat children are warned by the adults to stay away from the water after a rainy day. With no Miasma Streams, the Aqueduct is a tranquil passageway, with a few Royal Guards, a Mail Moogle and a Clavat woman (who has a tendency of rolling down the hill along with her pumpkins, allowing Layle to earn gil by saving her) being constantly around the area.
