Jaffa is a Jaffa who appeared in Sacrifices.
He was among a group of Jaffa resistant to Moloc. He informed Ista to set up meeting with all Jaffa resistant to Moloc ,which she agreed to and sent Teal'c and Rya'c. He and other Jaffa then met with Teal'c and informed him that their numbers were growing too large to conceal and in order to not risk being exposed Moloc would have to be killed soon. Just as Teal'c tries to convince them not to act prematurely, dozens of jaffa swarm in and kill everyone there except,Teal'c, Ry'ac and a Jaffa named Aron. ("Sacrifices")
