The Veo Lu Sluice is a gigantic water table from Final Fantasy Crystal Chronicles set in the northern part of the continent, near the city of Shella. This complex is the single source of water for the Jegon River, which feeds the rest of the continent.
The Sluice is operated by native pumpflowers, which have an unfortunate tendency to wither, thereby drying up most of the Jegon River. These flowers require some maintenance to keep healthy. The Sluice is also home to Lizard Men, Flans, and Gigan Toads. The sluice is guarded by a Golem, which has many the strong attacks to hit, freeze, light aflame, or knock you back with, all to hit anything humanoid or soft and fluffy.
Once Veo Lu Sluice enters it's 2nd cycle, the Jagon River will dry up. The boat will move to the Tipa Peninsula, granting permanent access to Leuda, even when the boat returns to the Jagon River. The drying of the river also grants free access to the Fields of Fum. To revive the Jagon River, one must simply cast Life on the large plants. Once they sprout a flower on their sides, they're alive again.
