James Clarke

 was a friend of Katherine Chambers from university. He was interested in the cyber conversion technology, and its use with The Forge. He kidnaps Tegan Jovanka in order to test out the system he has created, and cure her of the tumour. He backs up a copy of system, before Nathaniel Chambers destroys it and promptly disappears.

A version of system appears from his back up in St. Gart's Brookside Hospital. (BFA: The Harvest)
