Athan

From Memory Alpha, the free Star Trek reference

Athan was a Novan who distrusted Archer and refused to believe that the Novans were in danger due to water contamination.

After Malcolm Reed was wounded by gun fire from the Novans, Athan was in charge of the group that held him captive. After Jamin and Archer saved a young Novan from drowning, Jamin would convince Athan of the sincerity of Archer. Jamin agreed to assist his people in relocating, and had Reed released.

Athan was played by actor Brian Jacobs. His costume was sold in week 17 of the It's A Wrap! sale and auction (item#2577) for $212.50.
