xilbalba is incorrectly written, and should be written as "Xibalba" being its meaning:
The right thing is Xibalba. It is described in the Popol Vuh. It is the name given by the Mayans to the subterranean world or underworld which was governed by the disease ( Hun - Came ) and Vucub Came 41 death;. They are actually a series of mazes of underground rivers in the Yucatan Peninsula. Hidden place, place of the terror.
