Most of the tension during the Anathema invasion comes from anticipating their arrival rather than their actual attacks so much so that the mass hysteria from the public is actually more immediately dangerous than the Anathema themselves.

The Anathema's methods are very meticulous yet slow, so it is plausible for the Zi'vani to survive. Undoubtedly, there would be some among the Zi'vani who would be panicking at the situation.
