Organon is the star system used by the Syreen as an ambush for the Mycon. This is the last step in the Syreen mission. After recovering their ships for them, Talana will ask you to go to the Mycon homeworld at Epsilon Scorpii I. Tell them about Organon, and they will head there to make it a Shattered World. Unfortunately for them, the Syreen will be waiting and hit them hard.
