A Truth Read is when a magician uses his or her magic to enter the mind of another, and read their thoughts. The participant is willing to let the other person enter their mind.
The Guild's policy is that if a magician or novice makes a serious accusation against another, then the person who made the accusation must be willing to either submit to a truth read by one of the Higher Magicians, or to take back their accusation.
Another variation of the Truth Read is the Higher Magic technique of Mind Reading (knowledge of higher magic is not needed to accomplish this however), this practice is very common amongst Sachakan Higher Magicians, they use this skill especially when they want to read their slave's mind.

During the hearing for the accusation Sonea made to Lord Fergun, Lorlen read Sonea's mind in order to test if her accusation was true. During this Truth Read Lorlen found out that Akkarin was a Black Magician when he saw him drawing power from his servant, Takan.
