The man steps aside, motioning for you all to proceed him. The group is not too happy about this, but the choice is to follow or fight, so follow it is. Genithar manages to cast his spell without note.
The workshop is a less cluttered than the previous one, and probably sees less use. Its most interesting feature is the green glowing wall of energy along the southern wall. From this vantage point, you cannot make out what is on the other side, but you can probably guess.
A few others inhabit the room, all at the far side. One is a built-up tough, a bastard sword at his side. He leans pensively against a set of drawers, a smirk on his face. Next to him paces a very irritated man. A well fashioned breastplate covered his strong frame, and a sword the length of the elf's body can be seen slung over his back. Scars run down his arms, and another probable aberrant dragonmark blisters his face. The man's demeanor is obvious---he is pushed to the limit of his patience.
Then there is the kobold.
Sitting casually in a chair next to the green wall, a copy of The Inquisitive open, is a kobold with dusky violet scales. He wears what appears to be a very expensive set of glammerweave, sharply tailored. Where the other's clothes and manners suggest brutishness and violence, the kobold's suggest finery and style. But... just looking at it all put together sends a sense of... unease, menace. The aura is almost supernatural.
As the group shuffles in, the probable leader---the larger brute---pauses his pacing and looks the group over. He looks incredulous. "These? This collection of bruised weaklings and House trash? The old dwarf is a fool! We probably could shove them over!" He is about to say more when the kobold holds up its hand. The brute's mouth hangs open a moment, then he grinds his teeth in frustration.
The kobold folds the paper neatly and places it beside the chair. He speaks without obvious menace, but his voice is almost hypnotic, like something echoing in the recesses of your head. "Ah, the interlopers. When I was told of your presence, I must admit that I was surprised. My intelligence suggest this one"---Aldus?---"would not have the means to communicate with the outside world. No matter, I am sure they missed several things." The kobold does not glance at the brute, but the barb is surely directed at him.
"I am an independent contractor. Have no issue with you other than your infractions against my employer. But is possible we can help each other out. So I shall put it simply. My employer wants the information from the dwarf---the information he refuses to talk about---and you want the dwarf free. Let us see if we can reach an agreement."
