Final answer:
In "El Libro de la Vida," the departed go to either the vibrant La Tierra de los Muertos, if remembered by the living, or the desolate La Tierra de los Olvidados, if forgotten.
Step-by-step explanation:
In the animated film "El Libro de la Vida" (The Book of Life), which explores themes from Mexican folklore and mythology, the two mystical lands where the dead go are known as La Tierra de los Muertos (The Land of the Remembered) and La Tierra de los Olvidados (The Land of the Forgotten). The Land of the Remembered is a vibrant, joyful place where the spirits live as long as they are remembered by the living. In contrast, the Land of the Forgotten is a dark, desolate place where spirits reside if they are no longer remembered by anyone in the world of the living.
