Threats from Outside

From Shadow Academy

On an almost daily basis, the Shadow Academy faces what it considers "mundane" threats - rampaging ghosts and demons, vampire nests, werewolf attacks, even the occasional alien invasion - are all considered "just another day's work" for the Shadow Academy's Operations Branch.

There are, however, some threats to the balance of the two universes that are so insidious, so well hidden and so far-reaching that their presence is a constant threat to the purpose and aims of the Shadow Academy. These hidden conspiracies - sometimes known as the Invisibles - fight a nearly endless war with the Shadow Academy, seeking to destroy not only Earth itself - but everything that the agents of the Academy hold dear.

The Reptites

Intelligent reptiles are not unique in either the World of Light or the Nether-Realms, but the Reptites are truly a force to be reckoned with. Their point of origin is unknown, and all that is known is that they have extremely advanced technology and a burning hatred of humanity. To date, they have attempted several times to invade Earth, each time seeking - apparently - to terraform it into something they consider more habitable.
