Isabelle Adama is Joseph's and Sam's mother. She is married to William Adama Sr. She and her husband are members of the Ha'la'tha resistance on Tauron. The Ha'la'tha opposes the Heraclides forces because the Heracs oppress the people and subjugate them with harsh measures.
During a confrontation with the Heraclides police, she and her husband are killed. Their sons are now orphans. In their hiding place, the brothers pledge their loyalty to each other.
