Baktun:Twenty cycles of the Mayan calendar equal to 144,000 days or approximately 394 years.
Black Jade:Found only in a particular mine located in southern Mexico, this jade has very special supernatural properties, including the ability to absorb supernatural energy—in particular, god energy. When worn by humans, it is possible for them to have physical contact with a god. If injected, it can make a person addicted to doing bad things. If the jade is fueled with dark energy and then released, it can be used as a weapon. Chaam personally likes using it to polish his teeth.
Book of the Oracle of Delphi:This mystical text from 1400 BC is said to have been created by one of the great oracles at Delphi and can tell the future. As the events in present time change the future, the book’s pages magically rewrite themselves. The demigods use this book in Book #2 to figure out when and how to kill the vampire queen. Helena also reads it while their captive, and learns she must sacrifice her mortality to save Niccolo.
Cenote:Limestone sinkholes connected to a subterranean water system. They are found in Central America and southern Mexico and were once believed by the Mayans to be sacred portals to the afterlife. Such smart humans! They were right. Except cenotes are actually portals to the realm of the gods.
(If you have never seen a cenote, do a quick search on the Internet for “cenote photos,” and you’ll see how freaking cool they are!)
Demilords: (Spoiler alert for Book #2!) This is a group of immortal badass vampires who’ve been infused with the light of the gods. They are extremely difficult to kill and hate their jobs (killing Obscuros) almost as much as they hate the gods who control them.
Maaskab:Originally a cult of bloodthirsty Mayan priests who believed in the dark arts. It is rumored they are responsible for bringing down their entire civilization with their obsession for human sacrifices (mainly young female virgins). Once Chaam started making half-human children, he decided all firstborn males would make excellent Maaskab due to their proclivity for evil.
Mocos, Mobscuros, O’scabbies:Nicknames for when you join Maaskab with Obscuros to create a brand-new malevolent treat.
Obscuros:Evil vampires who do not live by the Pact and who like to dine on innocent humans since they really do taste the best.
The Pact:An agreement between the gods and good vampires that dictates the dos and don’ts. There are many parts to it, but the most important rules are vampires are not allowed to snack on good people (called Forbiddens), they must keep their existence a secret, and they are responsible for keeping any rogue vampires in check.
Payal:Although the gods can take humans to their realm and make them immortal, Payals are the true genetic offspring of the gods but are born mortal, just like their human mothers. Only firstborn children inherit the gods’ genes and manifest their traits. If the firstborn happens to be female, she is a Payal. If male, well… then you get something kind of yucky (see definition of Maaskab)!
The Tablet:A Mayan relic made of black jade. It has the power to create portals to other dimensions and to another moment in time.
Uchben:An ancient society of scholars and warriors who serve as the gods’ eyes and ears in the human world. They also do the books and manage the gods’ earthly assets.
Vamp-ubus, Incu-pire:The saucy combination of an incubus and a vampire.
