Xibalba

In Maya mythology, Xibalba (or Xibalbá) was a dangerous underworld, ruled by the demons Vucub Caquix and Hun Came. The road to it was steep, thorny and very forbidding.

Much of the Popol Vuh describes the adventures of the Maya Hero Twins in their struggle with the evil lords of Xibalba.

Alternative name: Xibalbay
