Ancient hand weapon
Small handheld weapon used by many Ancients during the era of the first siege of Atlantis ten thousand years ago. The weapon is capable of releasing an energy discharge that will render a human male unconscious. The device likely possesses a more powerful kill setting as well.
The weapon is similar in design to the Wraith transporter generator in the undercarriage of Darts. This hand weapon suggests that both Ancient and Wraith technology may share a common technological ancestry.
