Wraith Battering Device

The Wraith Battering Device is an experimental device developed on planet Vohl by the Wraith, for the purpose of giving the Wraith new ways to prepare and consume the life force of other beings.

When a person is placed inside the device, they are severely battered by the machine, slowly beating the subject to death. The moment the subject's skull cracks is particularly savored by the Wraith.

History
In 2004, in an experimental laboratory on Vohl, the Battering device was used on a Karran Honored One. By the time Lieutenant Aiden Ford and Teyla Emmagan arrived to rescue Major John Sheppard, the man who was in the device was already gone.

However, Sheppard pointed out the device to Ford, mentioning he thought it had held one of the Karrans and that they had to rescue them.
