Scry
From Ardrana
The scry spell allows the caster to see and hear events within an area on the order of miles, despite most obstructions. The spell requires a large bonfire, a pool of still water, a mass of clouds, or a section of smooth natural stone (depending on the element, if any, favored by the caster).
Upon casting the spell, the element forms a smooth polished mirror, unaffected by any outside disturbance. By concentrating on this mirror, the caster can call forth any scene currently occurring within the area of effect. Standing outside a castle, a caster could scry into a pool of water to see what is currently transpiring within the walls of the castle.
The spell provides a perfectly clear picture and normal sound just as if the wu jen were present where the scene is taking place. The communication is strictly one-way -- the wu jen cannot speak or otherwise influence the scene he is observing.
Spells cannot be passed through this mirror. The scrying is blocked by a thin coating of lead or gold that is at least 1/8-inch thick. Of course, magical protections likewise prevent the operation of a scry spell.
The element used as a spell focus returns to its original state at the conclusion of the spell.
Note: This spell originally appeared in this form in Oriental Adventures for Advanced Dungeons & Dragons (1st edition) from TSR. Its use here is for the purposes of providing context for the campaign only.
