James Clarke was a friend of Katherine Chambers from university who was secretly an operative of the Forge. He was interested in the cyber-conversion technology. On 22 September 2006, he kidnapped Tegan Jovanka to test out the System that he had created, and cure her of her tumour. He backed up a copy of System before Nathaniel Chambers destroyed it and promptly disappeared. (AUDIO: The Gathering)
A version of System created from his back up was used in St Gart's Brookside Hospital in 2021. (AUDIO: The Harvest)
