Tobras Jorn

The Tide Turns
When you enter the Armory in the ground level, you will meet some enemies cornering him:
 * Blood Tide Sorcerer: I can sense a door over here, but I can't seem to open it!
 * Blood Tide Creeper: Over here! Over here!
 * Blood Tide Pirate: You can't hide in there forever! Open this door before I get REALLY mad!

After you take care of the enemies, he will open the door for you:
 * Tobras Jorn: There you are! I knew you'd show up!

Talking to him will make he say:
 * Tobras Jorn: Oi, ! It's good to see you. I thought those pirates would get me for sure.
 * You: Uh, how do you know my name?
 * Tobras Jorn: Are you serious? Ever since you took on the Blood Tide your name's been goin' 'round the barracks like wildfire. It's an honor to meet you in person, it is!
 * You: I'd like your help - Greigur sent me to open the secret door to the steam tunnels.
 * Tobras Jorn: Working for the Marshal himself, eh? Very impressive!
 * Tobras Jorn: The lever is right over there in the corner. No one has used those tunnels in ages, but I imagine a hero like you can find a way through.
 * You: Thanks and good luck, Tobras!

After that dialogue, talking to him again will make him randomly say one of those lines:
 * Tobras Jorn: The lever is right over there. Good luck.
 * Tobras Jorn: The lever is right over there.
 * Tobras Jorn: Good luck, mate.
