Go through the Stowage Deck - description | Chapter 8: The Dawn's Light Thief Guide
Last update: 11 May 2016
After using the claw, Garrett will land onto moving platform which will take him to The Dawn's Light - Stowage Deck. You have to be very careful here, as the elevator stops at the balcony on the third level which is guarded by a single enemy with a crossbow. The best is to leave the beginning place, as the guard turns around from time to time and stands at the platform. If you didn't get away, crouch in one of the elevator's corner so he may not spot you. You can also rob him and take his three Coin Purses - 5+3+7G.
Of course, it'd be good to search thoroughly the whole third level. Eastern room is guarded by a single enemy. You have to also notice another enemy with a crossbow on the neighboring balcony. Don't let him see you (you can put out torches and candles). You can find in this area treasures as following: Tea Cup - 2G, Tea Pot - 12G and Surgical Scissors - 20G.
In the room on west from the beginning place, you find another guard but he should stay at his place. Steal his Coin Purses - 3+3G and try to lure him out from the desk by throwing items and putting out the light. It allows you to take Syringe - 10G and cut out The Court of Montonessi - Compassion, Foul from the frame (you have to have a razor). Finish exploration of this room by collecting the Magnifying Glass - 15G. What is more, I recommend to unlock door leading on the southern balcony where you can find a Gilded Bottle - 40G.
Before you start completing your current goal, it'd be good to search the lower levels. There are no stairs leading to the second level, but it's not a problem, because you can get there, for example, by grabbing the rope and sliding down or jumping over the balustrade and then walking or swooping the roof. The good place for that is the eastern upper balcony, because Garrett will land on the scaffold.
During walking through the second level, you have to beware of three new enemies who are set up here. Though they don't leave their positions, they are able to observe big area. Don't try to rob them, as they don't have anything to rob. On the other hand, try to find Magnifying Glass - 15G and look into the small eastern room (you need to use lockpicks so don't make a mistake!) where you find Gear - 6G, Urn - 35G and Surgical Scissors - 20G.
At the end, you should search the lowest level, where you can get by jumping into one of the holes on the second level. Avoid the single enemy patrolling this area and take his Coin Purses - 5+7G. When it comes to treasures, you can find here Gear - 15G, Telescope - 45G, Syringe - 10G, Urn - 15G and Surgical Scissors - 20G.
Remark - if you need to return on the second level, you can climb onto chests. On the third one you can climb via roof, where it's the flattest.
When you search the all three decks as you want, think about the way you want to reach Orion and Erin. There are three possible ways and I don't recommend the one in which you have to use the main entrance on the second level which is guarded by two guards. You'd have to distract them (e.g. by throwing items) and put out at least one torch.
The second variant includes using the upper balconies and for do so, you have to begin on the third level. Get an access to one of the small rooms in the western part of the location by placing yourself in the place shown on the screen above and use the Rope Arrow on the interactive latch. Sprint to the first rope, jump to the second one and when you get to the top, jump onto the closest balcony. Now head south, jumping to next upper platforms and to the small hole through which Garrett may jump.
The last option is to get through the lowest level, the one with a single guard. Put out some torches and then search the southern-west part of this level and you'll find a chest on which you can use the Wirecutter. Only now head for the door in the southern-east corner, open it, and go upstairs.
Door which is your current target is in the southern part of the location on the second level. If you've chosen the second or third option, you won't have to avoid any additional enemies. Head south and get to The Dawn's Light - Chapel where game displays a cut-scene of meeting with Orion and Erin.
