Proper Introductions
Piracy involves looting goods for profit, Jedi would never loot something for their own gain, unless they were headed toward the dark side. It wouldn't be piracy, unless the Jedi kept their enemies items for themselves instead of delivering them back to the original and legal owners, or just left the items alone and dealt with the threat.
But we could have common ground with someone that is for profit, if our goals are aligned such as stopping a slave trader, or taking down a despot that is causing problems for other grey characters.
As far as having a strong Sith presence, I wouldn't think the Council would send inexperienced Jedi for that yet. Perhaps just to investigate the situation, and it might lead to something like that later on. I'm not sure how experienced the rest of you are, but my character is barely more than a padawan (actually in my games he would be a young padawan at Force Rating 1).
