Okay! Looking it over: Sarmatian scrying is not so much fortune-telling as a means of clairvoyance and detection. It certainly can detect the presence or absence of water or other natural resources, of living creatures, or of spirits, magical wards, or magical forces on the High Tables.

Saving some time: spirits don't work like that here, and neither does magic, so it won't find those. For life or natural resources, you'll have to be more specific about what it is you're looking for, but it can definitely do that - it's just that one question will take about twelve uninterrupted hours of ritual and cost blood or other expensive or exhausting components or power.
