Under Henge

The Under Henge (also known as "The Pandorica Chamber") was a prison chamber containing the Pandorica under Stonehenge. During the Druids, the Cybermen were guarding the Pandorica. Parts of Cybermen such as an arm and a head were lying on the ground but simply coming back to life. When Amy was being attacked by the cyber-head, it shot a tranqualizer dart at her and suddenly a cyber-body with no arm put's the head back on, ready to kill Amy! Also the so-called "alliance" was forming to trap the Doctor into the Pandorica and the Earth came to it's end.
