Drain Knowledge

As indicated by the name, Drain Knowledge was a dark side ability used to extract knowledge out of a sentient without his or her consent.

Beyond simple reading of thoughts, the Drain Knowledge ability disrupted the Force to steal deep memories and information in a violent and merciless way. Such a process might damage the subject psychologically.

Jerec used this ability against Qu Rahn, learning that the location of the Valley of the Jedi rested with the dead Morgan Katarn.

Jacen Solo used it on former Queen Mother Ta'a Chume to find out if she had dealings with the Dark Nest to kill his child, Allana.
