Darth Sion, also known as the Lord of Pain, was a member of the Sith Triumvirate during the Old Republic era. Like Darth Nihilus and Meetra Surik, Sion was a wound in the force. His greatest strength, or weakness, is his inability to die permanently unless he allows it. However whenever he does die, his body decomposes further. Because his body is decomposing while he's alive, Sion is put through immense pain that only seems to get worse the longer he lives and the more injuries he sustains.
