The Hush is essentially international magical police – and they’re fairly scary.
Here’s what Katie has to say about them in Half-Shell Prophecies:
The Mythos does have magical police. They look different from world to world, from country to country, kingdom to kingdom, and People to People. But across worlds, across dimensions, over all government and jurisdiction, law enforcement takes only took one form: the Hush. The word originally came from some ancient word meaning sweeping or keeping clean, but over time, it morphed as words do—and at least in English, included the finger-to-the-lips gesture of silence. The Hush scared the crap out of me. Yes, there are other self-policing groups out there; mess with the Shape-shifter people who resemble jaguars. Like selkies, they remove their animal-skin to appear human. Their preturnatural senses make it seem like they have eyes in the backs of their heads, and... More of South America or the A shape-shifter being from Kenya, the Zimwi are people of the Darkness who transform from humanoid to leopard-like creatures. They have enormous smiles and magical drums in which they can... More of Kenya and you’ll find out really fast just what kind of justice they serve. But the Hush are inter-world; they’re multi-government, legally empowered across the board, committed to the single purpose of making sure the humans don’t know we exist.
The Hush are very organized. They accept anyone from any background, regardless of past or ancestry, and proceed to strip them of their personal identity to make perfect police. They usually do NOT err on the side of grace; they’re also rarely wrong, though when they are, it’s pretty much impossible to overturn a conviction.
Of note, members of the Hush are generally above reproach in every way; think of them as lawful good. Salis Kamialfaod is a half-troll member of The Hush, and the primary protagonist of the short story, NO REPARATIONS ARE EXPECTED AT THIS TIME. He had a brief run-in with Katie... More, a half-troll recruit, is one of its more typical members.
Lord-General Ramses Al-Benumm tá Oman, on the other hand, is somewhat less typical, as Name meaning: Night (Italian – he picked that one) Other names: Naktam; Night-child; Nox Aeterna; the Blood King; Lord of the Night Whispers; and of course, just Night. Notte by... More ensured Salis would find out.
