Two days after the attack on the temple, the Destroytian sailors hold a ceremony for the dead. It is a short ceremony with prayers said to a variety of deities, representing the faiths of the dead.
Pierre anoints the bodies with the First Water (they can't be brought back as undead or violated in any way after that).
Those sailors become more miserable after the attack. The deaths and the lack of things to do on the isle make life for them on it dull. Once you reach near to Port Talp, they get on the first ship to take them to the city.
Lieutenant Karl says farewell to everyone, but specifically to Nathan, "I hope you navigating the religion of Lakius goes well. It has been an experience serving with you."
The only other PC that he takes extra time with is Gabriel, who gets along with the sailors better than anyone else.
