You've received an urgent summons from (Nation NPC), who said she must meet with you to discuss a 'matter of life and death.' Best not to keep her waiting. Go to Port Royal to speak with Dillon Brinkworth, you find him dead in his office, 3 npcs appear in the office and say you killed him and accuse you of piracy. Go speak with the trade union bosses at The Company Office in Port Royal to defend yourself of the accusation. Choose the wise choices of talks with the npcs to defend yourself and accuse them, then kill the npcs and go back to Hamilton Noel in Port Royal to end the mission.
