"You're missing a few important details," he says. "From my perspective, it looks like this. Four days ago, it was the year 2997 ECE, humans were the only sapient species in the fairly widely colonized galaxy, and I was on my way out of the star system where I'd just successfully rescued a shipload of hostages from space pirates. I had a broken shoulder and a shattered hand from the fight. Then I woke up in an alley not far from here, looking up at Earth's extremely recognizable moon, and it was inexplicably 2005 and there were inexplicably vampires. My shy friend was the first person who found me, and he recommended vampirism as a cure for my injuries, which would otherwise have cost me the hand given the state of local medicine. I accepted the offer as described. And then it turned out I should've inquired more closely about the exact function of a soul. Now I'm - suffering a temporary impairment to my moral compass, which I hope to correct as soon as possible. Hence the research."
