Minder

“Any unstable reality field is potentially dangerous, even cataclysmic. So someone has to watch over it.”

A Minder is an individual who watches over an unstable reality field, keeping it contained, thus preventing them from affecting our reality. The task, however, affects the Minder due to the exposure to non-linear temporal perception, which also allows the Minder to experience future events. Like Slayers, Minders are chosen by a higher power.
