Fissure

A fissure is a crack on a wall that appears in A Link Between Worlds. It is used to travel between the two worlds, Hyrule and Lorule. Fissures start appearing all over Hyrule after the first transportation into Lorule through a fissure present in Hyrule Castle. They can only be accessed as a painting, so Ravio's Bracelet is necessary. These fissures are said to occur because Yuga started bringing Lorule and Hyrule closer by travelling between them. Their appearance is a thin slice in a wall surrounded by what appears to be a blotch of paint which is mostly black in color with multi- coloured patches. In Hyrule, the fissure emits darkness, whereas in Lorule, it emits light.
