Legends of Kyrael is a modern-day world that has developed to survive the incursion of Pokemon as a species and the replacement of many natural creatures with Pokemon equivalents. Pokemon are seen by some as close companions, by others as dangerous threats, and by many as weapons of warfare. As such, those who form affinities with them easily are closely monitored for signs that they may become a talented Trainer, for good or evil.
