Kingdom of Death
Mictlán is inspired by the origin of the Day of the Dead festival.
The civilizations of pre-Columbian Mexico, believed that the fate of the soul was defined by the way of dying; if it was on the battlefield or during birth the soul traveled to the paradise of the sun. If the death was by drowning, the destination was Tlalocan, paradise of the water. If the one who died was a baby, his soul went to the underworld where there was a huge ceiba with nipple-shaped fruits that fed him while waiting for the opportunity to return to earth in another birth.
If the death happened by natural causes, then the soul had to start a long and painful journey of 4 years, crossing 9 inhospitable and dangerous territories including by a huge and mighty river where only one dog acceded to help the dead person to cross it, only if the soul in Life was good with the dogs.
Finally arriving at Mictlán, the kingdom of death, where the reward was rest contemplating stunning sunsets.
