A voice boomed out from myriad sources. Human -- are you wearing a bomb, a pitifully weak explosive that you think can harm me? Did you bring one of your atomics, or is victory not worth such a price to you?
 
I am not so naive, Omnius. Heoma tossed her sweaty white hair over her shoulder. One person cannot possibly harm the great computer evermind. That requires a much more extensive military strike. I'm no more than one woman.
 
As the giant cymeks approached from adjoining corridors, Omnius simulated a laugh. Humans rarely admit the folly of their own actions.
 
I admitted no such thing. Heoma's skin was glowing red now, heated with unnatural energy. Static electricity made her pale hair wave like angry serpents. You have merely misjudged my purpose.
 
The doors opened and three monstrous cymeks glided in with graceful metal footsteps, as if savoring the capture of these humans. Heoma's bodyguards turned and opened fire, using the last of their ammunition to cripple one of the neo-cymeks in a single concerted attack! And they gripped arms in the Fremen fashion!
