Life can be found in every corner of the galaxy. Here is a list of them within the Star Wars: The Knights of the Old Republic. Some you can only locate if you are playing a cretin faction or even a cretin class. Others you will find in multiple places as they tend to travel the stars as you do. Lastly some characters will be in different places based on an event in progress for the week. Take note that while you exploring the universe some people just don't want to be found. That being said, use the filter and sort feature to help you find who you are looking for.
