Game and Story Use

• If someone knows the right rituals, he could use the portal to physically enter Xibalba while still alive and converse with the Mayan dead, gaining much occult knowledge in the process.
• Alternatively, intruders might accidentally (or deliberately) break the wards that keep the Mayan dead in Xibalba, thus releasing them to wreak havoc in the normal world.
  • This might trigger a localized zombie apocalypse.
• Give the character of the Mayan and Incan pantheons, their land of the dead might be well worth avoiding.
