I was nineteen when I returned to Mitar, to study at the city’s university. Originally, I’d planned to specialise in the ecopoiesis—and to study much closer to home—but in the end I’d had to accept the nearest thing on offer, geographically and intellectually: working with Barat, a Firmlander biologist whose real interest was native microfauna. “Angelic technology is a fascinating subject in its own right,” he told me. “But we can’t hope to work backwards and decipher terrestrial evolution from anything the Angels created. The best we can do is try to understand what Covenant’s own biosphere was like, before we arrived and disrupted it.”
I managed to persuade him to accept a compromise: my thesis would involve the impact of the ecopoiesis on the native microfauna. That would give me an excuse to study the Angels’ inventions, alongside the drab unicellular creatures that had inhabited Covenant for the last billion years.
“The impact of the ecopoiesis” was far too broad a subject, of course; with Barat’s help, I narrowed it down to one particular unresolved question. There had long been geological evidence that the surface waters of the ocean had become both more alkaline, and less oxygenated, as new species shifted the balance of dissolved gases. Some native species must have retreated from the wave of change, and perhaps some had been wiped out completely, but there was a thriving population of zooytes in the upper layers at present. So had they been there all along, adapting in situ? Or had they migrated from somewhere else?
Mitar’s distance from the coast was no real handicap in studying the ocean; the university mounted regular expeditions, and I had plenty of library and lab work to do before embarking on anything so obvious as gathering living samples in their natural habitat. What’s more, river water, and even rainwater, was teeming with closely related species, and since it was possible that these were the reservoirs from which the “ravaged” ocean had been re-colonised, I had plenty of subjects worth studying close at hand.
Barat set high standards, but he was no tyrant, and his other students made me feel welcome. I was homesick, but not morbidly so, and I took a kind of giddy pleasure from the vivid dreams and underlying sense of disorientation that living on land induced in me. I wasn’t exactly fulfilling my childhood ambition to uncover the secrets of the Angels—and I had fewer opportunities than I’d hoped to get side-tracked on the ecopoiesis itself—but once I started delving into the minutiae of Covenant’s original, wholly undesigned biochemistry, it turned out to be complex and elegant enough to hold my attention.
I was only miserable when I let myself think about sex. I didn’t want to end up like Daniel, so seeking out another Drowned person to marry was the last thing on my mind. But I couldn’t face the prospect of repeating my mistake with Lena; I had no intention of becoming physically intimate with anyone unless we were already close enough for me to tell them about the most important thing in my life.
