I've had Samantha come across enough people in threads now and think it's time I actually have her get closer to finding a master. Be warned, she is damaged. A lot. So letting you 'instantly' becoming her master wouldn't fit her character. While Samantha has a soft side she wouldn't be able to handle someone who simply bosses her around. She needs a challenge or someone soft who can make her talk.
Samantha would travel with you likely but this upcoming spring she is going to Lhavit for a while. As of right now she is in Alvadas.
If you need to get a feeling of just how bad Samantha is damage I have a couple threads that are great examples. Link et Link. They are long but it helps a little if you need to get a feel before you decide if you want to take up the challenge that is Samantha.
