Rescue an innocent citizen from the Persian Mercenaries.
When Scarlett first enters the Inner City, she will see a cut scene in which Persian Mercenaries arrest Eliana's husband on unspecified charges. Both Eliana and her (unnamed) husband will protest innocence. Scarlett will need to speak to Eliana to volunteer for this quest to rescue her husband.
During the Persian Occupation of the Inner City, Eliana can be found crying into the palms of her hands across the street from the Net of the Mask. After her husband is freed and the Persian occupation ends, Eliana can be found in the house right beside that spot.
Get Eliana's husband released from Persian captivity. (Scarlett doesn't actually know where the prisoner is being held, but it will turn out he's aboard The Claw, so this quest has a synergy her key The Pathway to the Claw quest.)
