Nabel Lake is a location in Atelier Rorona: The Alchemist of Arland. It takes five days to travel to Nabel Lake from Arland. If Rorona takes Iksel here while in the party, the Swirly Shell event flag will be triggered. Once Rorona has the recipe for Air Drops, she can go under the lake and gain access to the Lost City. The "To the Lake" event also takes place here.
