Drugs in various forms are woven throughout Ghosts of Innocence.
The most frequently recurring example, and important to the plot, is trylex. It removes all voluntary motor control and renders a person powerless to resist external suggestion. This places the victim totally in your power, as far as general physical actions goes. It has a nasty side-effect that any attempt to fight the drug results in mind-splitting pain.
Shayla uses trylex several times to drug victims, including the Emperor, and is hit with it once herself.
Nicadyne is a more everyday drug. A powerful stimulant, commonly used to overcome fatigue, it's a bit-player in the Ghosts pharmacopoeia, and makes several brief appearances.
Two nastier drugs make single, but decisive, entrances. Animastin destroys recent memory. One of Shayla's colleagues takes it to remove any possibility of giving away his actions under interrogation. Nacrolin is a feared poison which Shayla uses at the end of the story. More of that in a later post.
Many more unnamed drugs and poisons crop up throughout the story, illustrating my leaning towards writing about "softer" technologies.
It's not all spaceships and death rays!
