Star Sense

Question: How would you handle a blind Scion with the Stars purview? Since the boons require you to be able to see them, would she be completely banned from having it?

Not at all! Man, we should really fix the wording on those. In fact, I'm going to go do that right now.

The Stars purview depends upon a Scion being able to interact with the stars, but it doesn't necessarily have to be visual; if she can perceive them in some other way, she can still call upon their powers. It's a Perception + Awareness roll to perceive the stars, and while a Storyteller may impose a penalty on blind Scions depending on how they feel about enforcing blindness (-4 dice is usually a good number), if that Scion can make the roll, she's able to tell the stars are there. Her player is free to stunt however she wants to explain that happening, whether it's the faint sound of the cosmic song of the stars, her skin being so sensitive that she can feel their pale light on it, or just that she senses their presence above her and knows instinctively that they are there.

In general, blind Scions can do most things regular Scions can, just at a disadvantage due to their handicap. How well they're able to function and find things around them depends on their Perception, just like it does for any other Scion, so those with low Perception are hamstrung by their blindness and those with high have uncannily sharp other senses compensating for it. We've had both kinds in our games: Aurora, who could hear into space and feel the tiniest pinprick of the smallest star on her skin, and Jude, who despite wearing twelve pounds of glass lenses strapped to his head still couldn't see well enough to back the car out of the garage without running over one of his bandmates.

I'll make it a point to go through and change the word "see" in the Stars purview to something more appropriate, like "sense" or "perceive", though, to avoid confusion!
