Isabelle Adama was the mother of Joseph Adama and Sam Adama and was a native of Tauron. During the Tauron Civil War, Isabelle and her husband William were members of the Ha'la'tha resistance. The Adamas were involved in activities such as blowing up a grain silo belonging to the enemy. William believed this was a bad idea, but Isabelle disagreed. After a member of the Heracleides militia was killed outside their home, Herac soldiers led by Kolibri entered and found a gun from the altercation, which, unbeknownst to the elder two Adamas, had been brought in by their son Sam after he heard the shooting. The Heracs brutalized and killed Isabelle in an attempt to force William to divulge information (CAP: "The Dirteaters").
