[@TheUnknowable] Looking at the timeline between where [@AnnaBeth] said this was taking place(4BBY) and the Jedi Purge(19BBY), I think it fairly safe to say that they would both be Jedi Knights in some respect. For however much that matters after the fall of the Jedi Order :v

So potentially, or at least they would be a little more inclined to work together with your character and try to keep him out of the Empire's sights. That being said, one or both of the sisters are being hunted because they killed an officer of the Empire a few years back, so probably not the best company :v

On a side note, they will be using some non-standard lightsabers and crystals. Notably a lightsaber pike and curved cross-guard lightsaber.
