I always assume Norse runes when I thought of the staff/rod. However, Harry had prime opportunities to compare his runes to Norse runes when Gard uses her rune based magic and doesn't.
He does, in fact -- he looks at her stuff and remarks that he's familiar with Norse runes, but that he doesn't recognize Gard's runes.
And when Gard describes one of her rune tokens, it doesn't sound like any Norse rune I'm familiar with.
You guys seem pretty good at wood stuff. What do you with these creations once they’re complete?
That blasting rod and one staff of mine usually end up as cosplay props. The holly staff is too heavy (and pretty!) to hike with.
My other woodworking I use as walking sticks when I hike (well, one or two I use, I'm trying to sell the others).
