The biggest overarching mystery may be why all of these events are happening specifically in the present era. If the series repeatedly references legends, myths, forgotten civilizations, or supernatural history, there may be a single event connecting everything.

The eventual revelation could be that MY-TH is not merely fighting a villainous organization. The Rider may actually be part of an ancient cycle in which the same powers repeatedly appear, disappear, and return. The real mystery would then be whether MY-TH is destined to repeat the previous Riders’ fate—or finally break the cycle.
