“Xibalba is made of nine levels. Through these levels descends the Black Road, which reaches a wall made from the thorns of the ceiba tree. Beyond this wall begins a causeway that leads to the gates of the Black City and allows access to the Jade Palace. By the palace is a lake where the World Tree quenches some of its thirst, and at the bottom of the lake dwells the First Caiman, which swam in the primordial seas and whose head was severed when the world was newly born.”
