Hear Truth

With the Theurgy spell Hear Truth, a tool for covert interrogation is available.

Spell Description
One of the highest principles of the Theurgists is Truth and they thus never tell lies to others, even if it hurts. However, there are lots of people who don't hold this virtue in regard at all and lie openly for their own advantage. In order to deal with this significant problem, and not violate their also important oath of pacifism, the spell Hear Truth was invented by the order. Once cast, it for a limited time reveals all and any lie of the conversation partner, whispering the truth behind the spoken lies into the Theurgist's ears.

Trivia

 * There are exactly four people with whom the spell works: Orlok (all the time), Xavier (before Torwin dies), Aramina (only while Mordea is alive) and Cyrrus (plot).
 * The spell is plot-relevant, since otherwise the information about Torwin can not be obtained from Cyrrus.
