At the dawn of our time cycle, following closely after Earth had become repopulated after a great flood, seven immortal god men assassins appeared. War caused these demigods to become scattered throughout the planet. These shape-shifting enforcers grew tired of walking among uneducated humans, and soon began teaching men the ways of gods and magic. The seven were tasked with maintaining vigilance over earthly interactions, including those impacting dimensions of time and space. They decided to teach between beheadings, and in short order this instruction evolved into vigilantism.
Each assumed control of terrestrial locations, and they continue to oversee every dimensional fracture within their chosen realm. Humans in rebuilding civilizations who listened patiently to the teachers were allowed to live out their days in the region of their birth. Those people were few. The majority sought out darkness, which answered, and caused ripples to radiate throughout each new society. These ripples spread out like rings of water on a still pond when a pebble has been dropped. Each generation carries forth the resulting fluctuations caused by previous generations, and those that ask for help are eventually assisted and washed free of blame. These people are also few.
The frustrated immortal teachers slowly became more like the flock than the shepherd—then learned to be as wolves among the sheep—and ultimately became assassins feeding on their charges like hungry lions.
These assassins became known as The Fisher Kings.
