The voices in the other room cry out in surprise, followed immediately by "LOOK OUT!" in a strangely accented Dwarven. Three very short dark-skinned Dwarves appear from around the corner, dressed in sleeveless studded leather armor with straps hanging down below the waist to the knees to form a skirt of sorts over a coarse tan fabric; their shoes are an odd design that is essentially a closed-toe leather sandal, with leather strips wrapped around and around the ankle and shin to the knee, then buckled to metallic knee pads.
The one the furthest to your left has his armor dyed dark green, has a stone-worker's hammer at hanging at his right side, and holds a blowgun up but not to his mouth. His hair is blonde and thinning, worn long and braided behind him, with a short cropped beard that leaves his cheeks bare. The one furthest to your right's armor is dyed a deep brick red, with his own hammer at his side and blowgun ready. His hair is curly, short, and red, and his beard bushier than the one to the left, though his cheeks are also bare. The one in the middle is nearly white-haired, with hints of blonde still in his loose, stringy hair, which he has slicked back with some sort of animal fat. His face is bare but for a fu-manchu mustache which he both braids and ties beneath his chin. He also has a hammer at his side, but in his hand he holds an ornate stone spike, made of mithral. There's obviously a design to it, but his grip on it obscures the details.
He practically brandishes the spike toward Saul as he says in that oddly accented Draconic "What manner creature are you? Raptoran spy? Killoren sympathizer? Dragon's slave? What gives you right of passage in our tunnels?" (DC 17 Sense Motive check is appropriate)
