Deep breath, kobold, get your words in order, needing to pause for thought could botch the whole thing here. (Probably not, Satele's Satele, but it's not the kind of risk one takes while Speaking; better not to Speak at all than to Speak poorly for someone, given the choice.)
"So, the person I met was a Sith," half a beat pause, just enough to let that sink in, not enough to invite a response, "but I think they were a very unusual one; how they acted toward me didn't match at all with what I've read and heard about Sith. The most unusual thing was that they didn't attack me or even argue when I wouldn't teach them my magic - they asked, first thing, and offered to pay me whatever I wanted, and answered my questions about why they wanted it calmly and as far as I could tell truthfully, and they were disappointed when the answer was no, and that was that. They only used the force on me with my permission, and didn't mind explaining what they were doing beforehand, and didn't lie about it that I could tell. They didn't ask me to cast any spells that could be used as weapons, even though I'm sure it was pretty obvious that I didn't know enough to know that I should refuse to. Their people seemed - okay, well taken care of; intimidated, but I've been around people who thought their lives were in danger and it wasn't like that there. I'm not really sure what to make of it, but I think they might be an exception to the idea that all the Sith need to be exiled, and I'd like to at least try to find out."
