Hypnogazer

A hypnogazer was a device used to make others follow orders unwillingly by hypnotyzing them.

Characteristics
It was circular and about the size of an average Human's palm. the part which victims were hypnotyzed by was a set of nine equally sized very bright small lights. One light was in the center while the others surrounded it.

History
During the time of the clone wars, Bounty hunter Cad Bane was on a mission for Darth Sidous to gather force sensitive children. In one case, Bane used a hypnogazer by shining it into Mahtee Dunn's eyes to hypnotyze her into following his request. After previously refusing, she uncontrollably handed over her force-sensitive child, Wee Dunn, to him.

Behind the Scenes
The name hypnogazer clearly comes from the prefix hypno and the verb gaze.
