Tezcatlipoca (WTO)

Tezcatlipoca is the term the wraiths of the Flayed Lands use for the force of Oblivion. His opposite is Quetzalcoatl, who personified the higher self.

Overview
To the wraiths of Mesoamerica, Tezcatlipoca is a dark god who rules one half of the universe's cycle, acting as a force of change by destruction. His symbols were the evening star and the smoking mirror.

When Quetzalcoatl left Mesoamerica, Tezcatlipoca became the dominant force. Not content of one day simply being replaced again by his counterpart, he plotted to ensure his continued rule over the cycle. When his priests asked when the Feathered Serpent would return, he revealed the month, but not the year. This confusion lead to ceremonial greeting of the arriving conquistadors of Cortes and the accompaining Heretics, who would later be responsible for the fall of Ix Chel into the Tempest. Tezcatlipoca, in his drive to escape his fate, had become a corrupted figure who had disrupted the great cycle for his own selfish goals.

The Shadow inside every wraith reaped in the Flayed Lands is not merely an aspect of the wraith's being, it is part of the essence of Tezcatlipoca. Originally, the Shadow acted as counselor to coerce the wraith to follow the dark god, but never had an active hand and was opposed by the splinter of Quetzalcoatl. With the White God gone, Tezcatlipoca reigns unchecked in a wraith.
