at Kraken: oh dang what happened?
A lot of things happened. Embarking on a terrifying ocean means you're going to encounter a lot of zombie fish. And these zombie fish will fight your dwarves. And when you build your forts over the ocean, the zombies are going to crawl into it and murder Dwarves while they're eating/drinking/sleeping.
But that's not what brought Townbrush to ruin. The zombies are merely opportunists, moving in when the Fortress is in a state of disarray. I can attribute three main events to the fall of Townbrush; the attack of Shuturn, the attack of Eslo, and "The Sugar of Executing".
Shuturn the Occult Owner was an Ogre that attacked Townbrush in its early years, and became one of the greatest enemies of the Fortress. A series of unfortunate events, mainly due to a lack of military strength, allowed him to slaughter over 15 Dwarves. Most engravings depict him salughtering Dwarves with his favored tool of destruction, and octorpre skin backpack. He was the first major threat to Townbrush, grinding all work to a halt and spreading chaos through the fort.
Eslo Murkflies was a Forgotten Beast that attacked Townbrush many years after Shuturn. His destruction wasn't as noticeable. In truth, he only killed a handful of Dwarves and never left the Abyss to threaten the fort. But in doing so he paved the road for the downfall of Townbrush. Eslo had an [UNDIRECTED_DUST] attack. He would expel a huge cloud of dust. For some reason, the physcis involving dust are screwed up. The dust knocks everything it touches across the room, including Eslo himself. My miltiary couldn't fight such a threat. My 3 best soldier perished from colliding with obstacles. Only after heavily wounding himself was Eslo slain. These 3 soldiers were the glue holding the military of Townbrush together. Because of their death, the military suffered a steady stream of casualties agains the undead. This is what ultimately lead to the greatest disaster in Townbrush history.
"The Sugar of Executing" is the name given to a massacre caused by a Darnen ambush. The Darnen are a modded race, capable of flight, meaning they can bypass walls and traps. They can wield wepaons up to steel, but they have poor armor, meaning they're easy to kill provided the Dwarf fighting can dodge. None of my Dwarves could. Eslo had killed the best soldiers, the ones that had pushed the Darnen back in the past. The Darnen slaughtered the military, and then proceeded to rampage across the Fortress. Nothing could be done to stop them. In truth, I'm not sure why they left. I believe the trade caravan's guards may have seriously wounded them, so they fled. I'll never know for sure though. This attack drove Townbrush into true chaos. A great tantrum started, one that would last for almost a year. Dwarves killed each other in cold blood. Mothers went insane, and their babies died as a result. What little work that was accomplished only served to keep the Fortress from falling apart. I thought Townbrush would never piece itself back together.
A few months after the tantrum, and the Fortress is still in disarray. However, I am starting to make some progress, even if the undead are ruining most of it. Anyways, that's the history of the Townbrush. Here's the short version; a combined force of Ogres, Forgotten Beasts, Darnen, and undead fish pulled Townbrush into chaos.
