Not if you don't want to... they may have been separated.
For those of you who don't know what we're talking about, I once started a thread in Star Wars Roleplaying (in JediKnight Series) called "The Sith Hunters". Riebe was the leader of them, but (as the story goes in my head) they were killed off one by one. Riebe faked her death and disappeared.
These events took place long before our current story and will most likely be drawn out in bits and pieces in conversation with Riebe (and JM's char if he decides to put him in).
If you decide to use your char as well, please take note: The Sith Hunters are very old by now and would be reluctant to share their stories... they've been laughed at too many times when telling the story. As time goes on, you'll understand why.
