Upon completing Quest 09 you’ll be able to deliver one more letter for Akia. This time she has you going to Puerto Valor to seek out a man named Valentino. Once you gain access to the Salty Stallion, sail over to The Costa Valor and make for Puerto Valor to the south. Once in town, head to the the bar at the southeast to find a man sitting down reading a book. Speak to him to hand the letter over before returning to Akia to complete the quest.
