Magical Defenders of the Solar System
The solar system of the Realm of Rhydin defaults to a technological science fiction setting. It is cross-genre, though, so all fictional milieu are allowed: Star Wars, Star Trek, Mass Effect, et. al. Fantasy, too, but that is very rare since those characters already have a cross-genre setting of their own.
It is that rarity that I am focusing on.
I hypothesize that magical threats can and do physically arrive at the edge of the solar system. Being of fantastic origin, such a threat should be difficult-to-impossible to detect by technology. Even detected, perhaps not accepted or believed. Even believed, technology might not be able to counter the threat.
Thus a need for magical defenders in space. The problem lies in the tiny pool of potential recruits. Very few fantasy characters self-select to interact with the science fiction side of the Realm of Rhydin, let alone take a ride on a spaceship to Gateway Station in orbit.
