So, should the world-building of this story include the use of wands in magic?
Chiefly for the main characters, of course. I could make it just a thing for some techniques of magic that they don't use.
But, on reflection, just because the images I have of them is their drawing their wands -- a nice way to make danger clear -- doesn't mean it's anything but my having not filed off enough serial numbers.
I suspect that what should determine it is whether, in the future of the plot, it will be useful (for me) for them to be disarmed -- or for them to be able to disarm people. But as I am currently pantsing through the outline, that's not very useful now.
And it can be hard to work through a story when leaving a thread like that hanging.
