"I'm not a shaman."
It sighs. "Yes, yes you are. Just a different sort from the one in your head."
"How did you know about that?"
"Anyone with the sight will see it. They are discolorations in your aura, and will mark you as a target for certain types."
"A target?" You may have heard that wrong.
"Always with the questions! I'm sick of it!" He begins to disappear.
"WAIT! How do I get rid of them!?" He stops fading for a moment.
"You must find why they are staying."
"They're trapped. I... sort of ate them."
Though his face is as gaseous as the rest of him, you can see plainly the look of either horror or disgust he is giving.
"Ehhhh..."
"So, can you help me get rid of them?"
He vanishes.
After waiting for a moment, you become sure that he's gone for a while. You wonder what you should do now. Scratching you head, you decide to look around the fort. You wander the halls idly, passing through rooms and around corners.
At an intersection, one path becomes rough and stone-covered. Your curiosity piqued, you take that hall and predict that it is a mineshaft of some sort. You continue along with the pick marks on the walls. You wander the shafts for a while, and after a long time you see an alien blue luminescence that makes your head throb a little in the distance. Despite the pain, you continue closer.
You don't get close enough to see the source. You lay against a wall and fade into unconsciousness.
You are once again in the room of the goblins, but there is only the commander and the shaman left. They confront you.
"What are you doing?! My men are disappearing!" the commander screams into your face.
"What?" You can barely think. "I don't know. What's happening?" You put your arms over your head.
"The others. They are vanishing. You have something to do with it." The shaman, though quieter, is no kinder.
"I dunno. I was just walking toward this blue glow in the dwarves' mines." Every beat of your heart brings only more pain.
They look at each other. The shaman speaks, "Was the glow coming from a stone?"
The pain ebbs away and leaves anger. Rage. A blood red mist shades your vision. "I. don't. know." You struggle to keep control of your voice, and can feel your hands shaking. "You made me black out before I could see the source." The room changes around you. The walls blacken, the trees die and leave only rotten, dessicated husks. The pond turns to blood and the grassy moss turns into a floor of tiny, oozing spikes.
"Uh," the goblins' faces drain of color. "C-Calm down, now." The commander raises her hands in front of her. The shaman stays silent.
"What?" Their actions aren't helping. "Why would you be curious if it's a stone or not?" The prospect of annihilating them is a very attractive one.
"A legend." The shaman is doing very well to control his voice. "There is a story told to new shamans about how contacting the dead is easier near glowing blue pillars. I never thought it was true. Apparently it is. All of the others wanted to leave, so they left."
You calm down enough to revert the room back into a pleasant place. "That little piece of information would have been very helpful the last time I talked to you. Why do you bring it up only now?"
He shrugs.
