My theme for this year's A- Z Blogfest is DEATH (who I hope is like DEATH in Terry Pratchett's Discworld series): "...tall, thin (skeletal, as a matter of fact), and ALWAYS SPEAKS IN CAPITAL LETTERS. Generally shows up when you're dead, or just when he thinks you ought to be." Today we have X for Xibalba.
Xibalba is the name of the underworld in K'iche' Maya mythology, ruled by the Maya death gods and their helpers. Some say the entrance is a cave in the vicinity of Coban, Guatemala. Cave systems in nearby Belize have also been referred to as the entrance to Xibalba. It is described as a court below the surface of Earth ruled by the twelve Lords of Xibalba.
Excerpt from Hogfather by Terry Pratchett
HUMAN BEINGS MAKE LIFE SO INTERESTING. DO YOU KNOW, THAT IN A UNIVERSE
SO FULL OF WONDERS, THEY HAVE MANAGED TO INVENT BOREDOM.
