So, the thing about speaking to stones is that they don't have to speak back, and most of them don't have a lot to say. But earlier in our current "season," we were all out in these Wastelands outside the main city which are the remnants of areas damaged in a magical war. We were searching for someone we were tasked with finding, so my character decided to ask a nearby pile of rock if it had any awareness of other beings like us in the area. It didn't, but it let me know that there was a big void underneath (which turned out to hold the ruins of a library, a valuable find). I asked if I could do anything for it in exchange, and it told me that it used to be part of a decorative arch, but much of the rest of the arch was long gone, and it missed the rest of the stones from the arch. So I promised that if I found any other similar stones in the Wasteland, I would ask if they used to be part of an arch, and if so, to let them know that they were missed.
