Use the ladder to return to the first part of the ship, and dispatch the Voidlings that appear here. Go interact with the lifeboat afterwards, and agree to go rescue the others. If you act quick, or summon your incarnate near the oil barrel, you can intiate combat before the tentacle can ignite the oil and kill them both. Dispatch them, before deciding if you want to try getting the EXP from the captain and Magister Knight at the helm of the ship. You should proccede to the Deck now where you'll be attacked by a couple voidlings. Do not enter the deathfog if your character is living. Get that key and open the door with a skull painted on it to witness some tentacles breaking into the ship and releasing some deathfog. There will be a Magister with a note and key in their inventory behind a small wall of fire. Though you could simply kill them afterwards even with that being done. You should deal with the Source hand before that if you intend to kill those magisters, but it's entirely possible to persuade them as well preventing any combat from occurring. But don't forget to break into the locked room. On the next floor, there are a number of chests, magisters, and even barrels and crates to loot. Regardless of how you handle that situation, you can continue onwards to the next floor by witnessing Windigo go crazy. She will immediately kill all the magisters except for Siwan.

You could additionally open the door next to Payde by talking to him, and once all the Magisters are aggroed run in and bring Windigo into the fight. If you do want to kill them, you can be sneaky about it and close the doors allowing you to pick off Waters and Siwan without the others noticing, then possibly take on Cadoc and Marel at once if you are feeling brave, before trying to take on the larger group in the main Holding area. Once you are done with that, decide if you want to kill the magisters or not. So keep the important stuff in your own inventory, such as your backpack, resurrection scrolls, healing items, and perhaps most importantly at least one Bedroll. However, unlike the Early Access, NPCs do NOT retain everything you trade to them. Like starting armor, or weapons, or healing items. You can loot the areas you can get to including barrels and such to trade for things you do want. Except for Payde, do not talk to him yet. Regardless, you should start talking to the Magisters on the boat. I will not be including the personal quests of the Origin Characters in these sections but will make note of specific places where if you have an Origin Character on your team, you might need to be aware of certain things. You'll be collared which prevents Source Magic before your character even wakes up. This is where you will start after Character Creation (Maybe not for undead or Fane, Unsure yet).
