Some myths believed that killing a gorgon could bring the dead back to life. Can defeating ALL of the Gorgons revive Kabr and his team? Maybe it is also possibly to turn the Gorgons themselves into stone, creating a path of stepping stones to make it across the maze without touching the ground. The gorgon head attached to zues' shield (made by Perseus or Athena) still had the power to turn things to stone. They used it to turn atlas to stone, creating mountains. There are plenty of mountains of rock in the maze area. Maybe the Gorgons are used to reach a section that is otherwise unreachable. One myth also relayed that after killing a gorgon, Athena wore it's skin for protection. Maybe like radiant skin? How long are the effects of radiant skin and the extended duration of sun singer powers perk (can't remember the name); will they allow you to make it through the maze untouched? We don't know the exact make up of kabr's fireteam in terms of Titans, hunters and warlocks. Maybe there is a combination of the subclass powers that allow the Gorgons to be defeated easier. A Titan with a shield, a radiant skin warlock, a blade dancing hunter... All things mentioned (more or less) in mythology in connection with defeating Gorgons.
