The group I run for uses spirits or one of the mage types astrally projecting in order to do scouting. One of the things they want to do is have an Earth Elemental look for a secret underground base. With the search power making a request to find an underground manmade structure - especially if you were less than a klik away seems trivial. So, can spirits simply fly through the earth looking for things? If they came out into a sealed underground room that had no light source and nothing living could they tell? Can a mage see underground, determine whether he's in a chamber, or how would all that work?
Perhaps a better question may have been - how do you deal with astral scouting trips without getting heavy handed about mana barriers and other astral protection?
Thanks!
With a sweep of his...
