M'zel had strong beliefs about a Jaffa's right to make the choice of freedom for himself, and feared the ever-increasing influence of the Tau'ri over the Jaffa Rebellion. He himself was once in the service of Heru'ur, and was one of the many absorbed into Apophis' army when Apophis killed Heru'ur. After Apophis' death, M'zel eventually joined the young Jaffa Rebellion.
