Awesome! Before I get started I had two main questions for ya! 

The first is that for the character I have in mind, I had the idea of her having an adoptive sister who could be on the dark side of things for a potential story point for her later. I know it's one character per person, so the question is more if down the line we can have second characters or npcs to pull things like this?

The second is for her Saber, I had the idea of Dual Sabers that can be linked together into Saberstaff (Double Bladed). Obviously she would be building this thing herself as she's fairly tech-inclined. Would that be allowed?

I am going to say for the first one, I will say no to the second char but yes to the npc part. So your char's adoptive sister can be an npc that you could play as when the time is right. 

For the linked lightsaber, I will allow it just make it a good reason how she has one.
