UNC: Hostile Takeover

This side quest is obtained in the Citadel from outside the emporium. Once you become a spectre, head there and speak to Helena Blake. She will explain that she wants two individuals and their operations eliminated. She gives you the position of the two people, and then a third location at which to meet her once the job is done.

The bases are located in the Han and Dis systems. Once the 2 smuggler bases are cleared, head to the Fortuna system to find Helena Blake for your reward and/or her removal!
