Shrine of Chaos

The Shrine of Chaos is located on the Serpent Isle and appears in Ultima VII Part Two.

Description
The heartpiece of the underground city of Skullcrusher is the Shrine of Chaos, also known as the Grand Shrine of Chaos. It is the central place of the chaos-part of the religion of the Ophidians. The shrine also houses the Wall of Lights, allowing the Hierophant to enter the Void and consult the Chaos Serpent. However, to actually reach the wall, one first has to walk through a secret door in the main chamber. This was done to keep away intruders from this most important place

After all followers of Chaos were slaughtered in the War of Imbalance, the Shrine became forgotten. It was only rediscovered centuries later, when the Avatar used this place to fuse the Banes of Chaos back together into the Chaos Serpent, using the Wall of Lights to return it to the void. Once that was done, the shrine returned to the mists of history.

Trivia

 * It is a little strange, that the pedestals for re-uniting the Chaos Serpent are present in the shrine, since not only could the inhabitants of Skullcrusher not have imagined the need, but they were all killed right at the start of the war.
