Nighttempest had been relatively peaceful for 3 years despite being situated in an untamed, scorching rocky wasteland. They were pursuing a new dawn of dwarven civilization after contact with the Mountainhomes were lost. It flourished and a new king was crowned, either by succession or divine right.
Traders came and went. Food and drink filled the inhabitants with satiation. Potters were pounding out a metaphorical flood of earthenware, powered by recently installed magma kilns. Smiths were honing their skills until they could perfect the metalwork into glorious steel armor and weapons for the military trainees. However, the concern of the lack of passive defenses were growing as the Gauntlet lay unfinished. Then again, no siege armies had ever laid their eyes upon the fort and there were no signs of hostile wildlife, barring the confused Great Horned Owl men. Even digging into caverns were uneventful. The one Gorlak seemed content to sit on his mushroom.
It all came crashing down when traders grew so mesmerized by our food and drink, our prosperity, that their minds couldn't handle the jealousy and drove them insane. A horse went berserk. The bridge leading to the depot was designated as closed but the tide of dwarves descending upon the traders to see what was happening forced that order to be cancelled. Alas, the lever had been pulled and several dwarves were flung across the depot with major injuries, some were crushed by the descending bridge. With nary a hospital nor a well in sight, a hasty effort was made to set up both. But construction time down in the caverns were too long as the first injured dwarves were unable to sate their thirst.
This angered the already weary militia and fist fights killed more dwarves.
Lo' and behold as Nighttempest descends into chaos in a tantrum spiral.
EDIT: Most of the dwarves are now fighting in the barracks. This will be fun.
