For Dr. Thomas Harburg, Dr. Kathy Crispell, and Dr. Daniel Oseran. Without their keen eyes and sharp judgment (not to mention scalpels), Andy might have had to fly this mission solo as an unjoined literary life-form.

Acknowledgments

The authors owe a debt of gratitude to: Christopher Teague and René Echevarria, who first established the truth behind Trill symbiosis (DS9 “Equilibrium”); Robert Sabaroff and Tracy Tormé, who introduced the alien parasites that infiltrated Starfleet in 2364 (TNG “Conspiracy”); S.D. Perry and Robert Simpson, who gave us the ever-vigilant Gard (“Allegro Ouroboros in D Minor” from the Lives of Daxanthology); the conjoined literary entity known as L. A. Graf (Karen Rose Cer-cone and Julia Ecklar), who unwittingly did some geographical, pharmacological, and zoological spadework for us (“Reflections” from the Lives of Daxanthology); Diane Duane, whose novel Intellivoreprovided some inspiring scenery; John J. Or-dover, David Mack, and Andrew Currie, who helped set up the contemporary political climate on Trill (Wildstorm’s Divided We Fallcomics miniseries); the aforementioned S. D. Perry, who embellished the histories of the symbiont and parasite species in previous volumes of this series (“Sins of the Mother” from the Lives of Daxanthology and the novel Unity); Michael Jan Friedman, for whom we nicknamed one of our Guardians; Ronald D. Moore and Joe Menosky, who introduced a certain fossil civilization (TNG’s “The Chase”); Jeff Lang, who took good care of one of our favorite supporting characters during his tenure aboard the U.S.S. Enterprise-E(in his Next Generationnovel Immortal Coil); Scott Anderson and Scott Gutierrez, both of whom furnished some much-appreciated scientific background information regarding symbiosis and parasitism; Marco Palmieri, editor extraordinaire; and Rick Berman, Michael Piller, Ira Steven Behr, and Gene Roddenberry, the giants upon whose shoulders we stand.

Historian’s Note

This story is set in early October 2376, approximately one week after the conclusion of the Star Trek: Deep Space Ninenovel Unity.

We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break, our bonds of affection. The mystic chords of memory, stretching from every battle-field, and patriot grave, to every living heart and hearth-stone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature.

—ABRAHAM LINCOLN, FIRST INAUGURAL ADDRESS, MARCH 4, 1861

Dante could not have crafted a more explicit version of hell than the one that existed in this place. As a doctor, Julian Bashir was used to trauma and suffering—he had dealt with severe episodes of both during the Dominion War—but those chaotic, bloody moments had not been entirely unexpected.

Here, however, in the bedlam of Trill’s Manev Central Hospital, things seemed very different. As the overflowing triage center filled with cacophonous screams and tortured wails, Bashir and the other physicians and medics struggled against a tide of death whose source had been both surprising and invisible.

And though Bashir’s medical conscience did not want to admit his own personal fears, the worst part for him was having no way to know whether Ezri had survived the initial bioelectric attacks—or even if she was in danger at all. But as Trill society continued to collapse around him, and reports kept coming in of hundreds—or maybe thousands—more casualties, he could only respond to the unfolding crisis as best he could, while striving to avoid considering the personal loss he might have to face in the very near future.

A pair of med-techs attempted to move a hover-gurney through the corridor as panicked personnel moved quickly out of its path.
