Received from: Viscount Marlow Dumar [Hightown - Viscount's Keep]
Step 1: Talking with Arishok
You will receive this mission automatically from Viscount Marlow Dumar, with whom you will speak after returning from the Deep Roads and therefore ending The Deep Roads Expedition quest. Go to [Docks] during daytime and enter the Qunari camp. Head to where Arishok is #1 (M19, 8) to initiate a talk. From him you will learn that Javaris, the dwarf with who you have worked during Blackpowder Promise is suspected of stealing a poisonous gas. If you have Varric if your team, you can ask him if he knows where Javaris might be #2. However it's not necessary, as even without him you will be sent to Darktown.
Step 2: Finding Javaris
Now head to [Darktown] and examine its central part, paying a visit to Coterie Barker #1 (M23, 12). Dialogue options don't pay have any relevance here, as either way you will learn that Javaris left town. Stay in Darktown and go to its southern part. Find a low-visible hatch (M23, 13) leading to [Smuggler's Cut] #2 (M63, 1).
It's a good idea to command your party members to stay by the starting point. Go down yourself and encourage the enemies to follow you to the very top. Attack the Carta Thugs #1, but look out for the Carta Assassin, who will soon join the battle #2. Exterminating him quickly should be a priority.
The first enemy group can be also surprised in a different way. You would have to go to the lower level and choose the passage leading to the south #1. It would let you get to a location with Poisonous and Corrupter Spiders. After eliminating the monsters you would be able to stand on a pressure plate, which would cause flames to appear #2. In my opinion it's completely unnecessary, so it's better to stick to the previous option (of course exploring the whole area is suggested).
After eliminating the first Carta group, use the passage leading north #1. As you have probably noticed, there are more enemies below. Unfortunately you can't attack them from where you are, so head to the western door #2. Use the stairs to get to the lower level.
I'd suggest stopping the team once again and attracting single enemies (M63, 2). Defeating them here will be easier #1 and you won't have to fear being surrounded. Try to eliminate all the enemies using this method, looking out for the assassins #2.
After eliminating the enemies go inside the main room which was previously occupied by them and head to the north-east #1. Keep going north, eliminating single enemies (inter alia Mercenary Archers) that will cross your way. However look out for a big group which is going to surprise you by the cave exit #2.
After the fight it's worth to take a look around, opening a chest (M63, 3) with an item connected with a new quest #1. In the end head north and choose the passage (M63, 4) leading to [Smuggler's Cut - Outside Smuggler's Cut] #2 (M64, 1).
Companion quest unlocked: A Ship for Isabela
Right after getting to the surface you will be forced into a new fight. Start off by attacking the Mercenaries and Mercenary Archers (M64, 2), remembering that some of them will run out of the cave #1. Additionally stay cautious as there will also be a Mercenary Assassin #2 and of course it's best to eliminate him as fast as possible.
Step 3: Meeting with Javaris
You will meet with Javaris right after dealing with the mercenaries #1. The dwarf will ensure you that he doesn't have the gas, which is in possession of a certain elf who tried to kill him. In the end you will have to decide what to do with Javaris. You can:
- Let him go (upper right dialogue option)
- Kill him (lower right dialogue option) #2
