Quick question, if my planned character's homeworld is just some random planet in some random area, could I just make up the name and place? Or would I have to search for a canon location?

I don't see why you wouldn't be going with an established world, I mean if you're going human there are plenty of planets to chose from. If you're going alien the same, most species despite having home worlds had people all over the galaxy. 

It makes little difference it's just a tidbit I want for nefarious reasons. If you want help choosing a planet just ask.
