A recap of the end of the mission:
Having taken the Viper fleet ship (the red viper to be precise), you set about a plan to capture the ship. Captain Ispolis , having come up along side the ship, yells over that he wants to get out now. "We already have a great bounty, lets take the Kakushin and the prisoners and sail to port." He collects the crew and the prisoners you have and sails away. You are left on the viper ship with those who are willing to volunteer (basically most of the PCs). Midiyro stays (katana wielding Horarian) as does Len the Doctor's Mate. No one else is willing to for one reason or another.
You sail straight, working on a plan to fix the rudder as the other Viper shadows you once they have picked up the dingy with the escaping crew of this ship. Exploring this ship, you clean out the captain's quarters and find little else. The gun deck was gutted by the fire and the lowest decks were cleaned out. Again, it seems as if the Ship's Mage, Quartermaster, and Steward were tasked with escaping and taking everything of value when something like this happens. There is a half hour of down time as the ships are more or less stopped picking up people before the chase begins. (Note to list all of the magic items you find on the captain and other captured or dead crew). Those on the gun deck have been cleaned of stuff.
The Pride and the Orca sail at a distance and watch, the sun is still an hour or more away. The Silver Viper come alongside your Viper, sailing parallel and waiting. You take stock and find the cannon to be mostly fouled, with most repairable given the right crew and materials. Ispolis took the lesser captured crew (only six), while allowing you to keep the captain. With the sun going to rise in a half hour, the other Viper ship begins to fire upon your viper and close. As they begin to fire, Tsunami comes under attack from swarms of vipers. At a distance, through a spyglass, you can see preparations being made on the other viper. There crew along with the surviving crew of this ship are on deck, readying for battle. You see four ogre sized creatures on their deck as well.
Sensing the pressure and realizing that it is unlikely you can reach Port Talp with the ship intact, you make the decision to scuttle the ship and get back to the Pride. You find a dingy and begin to load up on the side away from the other viper ship. You explode the remaining powder on the bottom deck, blowing a hole. You spend five minutes cutting everything and smashing everything else. You carry away everything you can and get the dingy. The other viper ship does not give chase. In the distance, as the sun begins to rise. One of the crew spots a flag run up the mast of the other viper ship. The flag is in red and purple and has to characters on it:
復讐
Isyawi says, "That means vengeance. They are swearing an oath to take vengeance upon us." This unnerves many of the crew as the Shelleshe oath of vengeance is always carried out; according the sailing lore. Most of those that are unnerved eventually calm themselves, but some make it clear they will not get on the ship again after you reach Port Talp.
You reach the Orca and take control of the ship from Lewis. Two days later, you reach Port Talp on the 3rd day of the 12th month of 787. The city looks fine. There are three other corsair ships in port.
