Henry Smythe-Peterwald the Thirteenth was a member of a family antagonistic to the Longknifes.
Henry arrived on Olympia during the humanitarian mission. He brought some new equipment that proved helpful but almost deadly to Kris Longknife. It later seemed that there were more than one reason for his visit. He claimed to be an only child.
Henry arrived on Hikila at, for him, a very opportune time. When asked by Kris Longknife if he had any control over the activities of terrorists who had attacked a conference, he referred to the terrorists as "freedom fighters."
