Wanted: Treasure and Fame
Window of Deception
A glance through this fine glass window reveals whatever you desire.
Wondrous Item 680 gp
Power (At-Will ✦ Illusion): Standard Action. You create an illusion seen by any creature looking through the window. The illusion is static and remains until the window is broken or opened, or until you or another creature changes the illusion or ends it with another standard action. When no illusion is presented, creatures see through the window normally. The window can maintain a separate illusion in each direction, and a character using the window can change either or both at once.
