Ictus
From Perpetuum
Earth’s closest analogy to the Ictus are the dark assassins of medieval Catholic church - secretive, plotting, humble, and terrible when met in anger. The “touch” of the Ictus is something feared by the Nuimqol and Thelodica equally, and even Syndicate Agents who control the Ictus say that a certain chill sits in their bones for days after.
