You walk to the kitchens, and take a large stack of plates [only steel, it seems, so they won't shatter on impact or even activation, probably, unless you could find a smith aboard the ship who could turn the steel martensitic, leaving it more brittle, but you don't really even know enough about the runestone magics to be sure that that would be a good thing, and you doubt that airships have smithies].
You look at the frost runes you have with you in your backpack for the arrangement of runes:
Primary rune on the front, with two smaller runes inside it, shattering on the left, activation on the right, with an even smaller rune for what you think is pressure to its right, based on what you saw when you used the runestones against the skeletons. Then again, it could have been a sonic rune. On the back, there's an inhibition rune, with a deactivation rune inside it, and a smaller heat rune to the right of the deactivation rune.
You think you can replicate the runes with some practice, so first you get to drawing them individually on paper. However, you soon remember that you have to know their names in order to enchant the plates with these runes! Back to the library, to look up information on the runes used in runestones.
