The Tenzerai was an event of major proportions that occurred briefly, yet encompassed the entire world. It was triggered by the interaction of an empowered individual attempting to manipulate the ley grid of Erlyse during an experiment of their own design at the end of the M'trosk Renn cycle. This experiment resulted in a violent eruption of Ley energy, which also created a low level shock wave that traveled across the surface of, and through the very core of the planet. While in transit, this energy seemed to target very specific individuals that belonged to bloodlines which held political influence and enhanced the genetics of these individuals in relatively minor, but impactful ways. Descendants of these bloodlines were not empowered like people who discovered a Ley Font, but did gain increases in physical capacities such as enhanced strength, agility, endurance and senses, as well as a vast boost in mental acuity. Individuals from these bloodlines became known as the "ley touched" by the Djinn, compared to the "ley saturated" for those empowered directly from a Font. These descendants would go on to become unfortunate targets for a cult dedicated to keeping balance in the world's power hierarchy as much as possible.
