>Keep it held up.
>Silent Pray to Shizuha she doesn't hit anything if she's looking at the stone and not where she is going.
>You keep the lodestone held before you. Reimu glances at it on occasion while driving, sometimes turning onto a different road to gauge how it moves. The movement isn't much, at first, but is definitely detectable.
>You decide to offer a silent prayer to a comparatively inoffensive deity. Reimu doesn't seem particularly perturbed by the distraction, but this isn't entirely comforting.
>Eventually, the movement in the lodestone becomes greater; you seem to be narrowing it down. And none too soon, either. Your arm is getting kind of tired of holding it up. Eventually, you drive around a small block and notice the lodestone spin full circle. Reimu doubles back and pulls into a lot in front of a very large structure. It is not as tall as some of the structures you saw across the skyline, but its footprint is larger. You think it would remind you a castle, were its architecture not so different. It is a plain, heavy-set building, mostly light brown in color, with a few large banks of windows. Reimu looks at it and frowns.
