I shouldn't be here, thought Urist McPeasantDwarf.
He was in the lower tunnels, as if drawn by a mysterious force. The tunnels had been mostly sealed off and were off-limits as the last exits were to be closed over the next week. And yet there he was, heading through the dim tunnels as, by this point, over half of the torches had burnt out since the lower areas of the mines were declared abandoned.
They weren't depleted initially, but the Legendary Miners were quite thurough in their work. That, and there was a breach in one of the walls. The council was very nervous about such a gap, when they had spent six years creating a nearly impenetrable defense on the main entrance. Any other entrance could allow an unwanted easy route for any fools brave, or dumb, enough to try to breach the walls of the fort.
When the area was sealed off, they would flood it with magma to ensure that nobody could use it as a back door. However, that was over a week away, so Urist didn't have a good enough reason to resist the force.
Long hours of wandering through the darkness, and Urist felt he was approaching his goal. Either that, or he was just happy to be nearing an exit, as the darkness had done nothing to make him feel that coming down here was a good idea.
Suddenly though, he noticed a faint glow in the distance. Curiously, and increasingly hesitantly, he progressed towards what seemed to be a torch held by a shadowy figure.
It spoke, in a voice that chilled Urist to the booze-soaked bones, made worse by the two faintly glowing green points that could only be it's eyes. "I am Qwertyuiopas, the weilder of the ‼sock‼. You shall die for your crimes against the stone!"
Scared, Urist turned to flee. Knowing that what he was drawn by was not just another piece of unclaimed clothing, he had no hesitation to retreat to his room, safely on the other side of the fortress.
However, he was too slow. A blur straked past him, extinguishing the nearby torch with it's wind, and an instant later, Urist's life.
The dwarves would pay for mining the mountain until it was devoid of all valuable substances. They would pay.
And this time it wouldn't be from the pits that they had left alone this time.
