*The S-S sighs a sad sigh.*
S-S: I guess that I will have to explain things then. Not that long ago, we were once Dual-Changers, like your four friends here. Some of us lived here once, others lived far, far, away. But, regardless of where we were, we were a peaceful species...until the day when they arrived.
They?
S-S: A group of young, naive, scientists, who were looking for something to do. At least, I think that were scientists. Thinking back now, I don't know what they were. Continuing, they came across this city and saw us and thought of us as animals. As non-sentient beings. So they captured a few of us for study.
Edit: *A S-J slides her now feminine voice, rough with age, into the S-S's pause in speech.* There is no need to be afraid youngsters. We mean you no harm. These scientists ran tests on us. All sorts of tests. With large needles and...*shivers compulsively*...other horrible things. They let some of the other Dual-Changers go when they were finished testing them, but not us.
