Historically, species were denied medallions because they were deemed to dangerous to be able to hide as human, the logic was that the medallion would basically be a way for them to hunt other sapient species in an easy way or do other damaging things and then disappear into the shadows. Traditionally "dangerous" creatures like manticores, harpies, gorgons, chimeras, nemean lions (until Jocasta made nemean medallion, of course) were refused medallions.

But then there are some species that just lived in places unaccessible to sphinxes while they were making medallions, so they didn't have any particular reputation for being dangerous, they just weren't around when the medallions were being handed out. However, the large majority of the medallioned population sees people without medallions as dangerous monsters, because if they weren't dangerous monsters, then they'd have medallions!

And that doesn't even begin to cover how members of "dangerous" species aren't usually actually dangerous! Like Madam U or Abby in the Underground, or Ike. Anyway, there's a reason why Michelle is the center of attention these days.

Hope you enjoyed that info dump!
