Recall

Regular 
The subject recalls a single forgotten or obscured fact or event as if he had Photographic Memory. The penalties given under Time modifiers apply, based on the time since the forgotten event occurred. 
Eidetic Memory (M) gives a +5 bonus; Photographic Memory gives a +10 bonus (though individuals with Photographic Memory will only need this spell to restore unnaturally removed memories). Only a critical success allows a magically blocked memory to be recalled. A critical failure could cause a false or distorted memory, or eradicate the memory beyond hope of future recovery! 
This is also a Mind Control spell.

Duration: 1 day. Afterwards, the memory fades as per the Magic and Abilities/Spells/Knowledge Spells/Memorize spell.
