Images of the Past

Regular 
When cast on a mirror or reflective surface, this spell “plays back” whatever images it may have “seen” in the past. The caster specifies the moment from which to start viewing (“Let us see what happened in this room a year ago . . . ”). The Time modifiers (p. 81) apply. Each time this spell is cast for the same time period, there is a further -1 penalty to skill. A critical failure will wipe away the object’s “memory” of that time period. 
GMs may also allow the spell to be cast on any floor, wall or object, the “playback” manifesting itself as a Simple Illusion.

Duration: 1 minute. 
Cost: 3 to cast. 3 to maintain. The magnitude of the Time modifier is added to the cost, so the spell costs 3 (3 + 0) for “within a minute,” but would cost 8 (3 + 5) for “4 to 40 days.” 
Time to cast: 10 seconds. 
Prerequisites: Magery 2, History, and Voices.
