Deep beneath the throne room was a cylindrical corridor that terminated in a round wall. Growing from the top of the wall was the Embrace's venomous vines, which leached down towards the polished floor. The steps leading up to the torture rack were of the same black stone, and the room was lit by dim red lights.
It was within this chamber that Darth Krayt tortured Cade Skywalker, hoping to bring him closer to the dark side.
