D&D: Ask the mirror to locate an unknown item of value
From Create Your Own Story
"Show me where I can find an item of great power" you order.
The mirror ripples and shows you the tower of an unknown to you wizard, the image then descends as if a great scrying point was going down below the tower.
After a few minutes you see your prize, it's a golden wand sitting upon an altar of some sort in a large room filled with plants that you do not recognize.
Do you:
D&D: Research the tower and it's owner before travelling there
D&D: Hire someone who knows of the tower and the area it is in
