So, after a reformat, I decided to start playing DF a bit again. Created a new world, and started searching for sites.
Huh, this world only had 3 sites that matched my search requests. Well, lets take a look. Hey, this one's perfect! Tons of shallow and deep metals, soil, clay, one Biome heavily forested. No Aquifer, but fresh water available via a brook.
Only problem is that there are three different biomes. One is only medium Savagery (just plain Wilderness I think?) and had the most stuff, but the other two were both haunted. I've never Embarked in an evil biome before...well, for long.
What the heck, Why not? I embark.
Ah, Dwarven paradise. Tetrahedrite, Tin, native gold and silver, Galena. Iron in two forms, AND Flux! What, I wonder, would the catch be to these riches? I soon found out.
I got a basic fort carved out of the rock and dirt and got everyone inside when I got an alert about a cloud of evil vapor drifting around. I gave the order that no dwarf is to leave and zipped over to have a look at what horrific fate would befall whatever the cloud touches.
I think it was a Cavy, actually, that the first cloud engulfed and turned into an Evil Vapor Husk. "Oh wow, this embark is really going to be Fun..." I thought to myself as I started preparing.
We dug down, set up farms and crafts and kitchens. We endured being chased by Yak Corpses and our burial ground grew, and grew. But we endured and spread and new migrants were always available to replace the losses. Rounds and rounds of hysterical laughter ensued after the discovery of a Mussel shell clacking around on the ground, looking for the mussel that used to live there. A victim of the evil Biome's borders powers of reanimation.
After cleaning up the remains of those fallen in the last goblin siege, the disaster that had been inevitable from the first planning stages decided it was time to strike. In the large room where both the stairs down to the magma forges, and the burial ground were laid out, something awoke. I sent the military to deal with the zombie I had assumed had somehow managed to slip past my traps and into the passages. By the time I realized the truth it was too late.
My burial ground had expanded too far, it crossed over the line into an evil biome and now dwarves and dwarf parts were reanimating faster than they could be disposed of in a more permanent way, or relocated away from the reanimation zone. Outside our gates were three angry Yak husks. There was no hope for help, no way to seal off the threat until more militia could be trained and armed, because all of our weapons and armor were through the zombies, as well as the forges and most of the metal ores.
Your Settlement has been abandoned.
Quite proud of the fact I managed to make that one last five years, since most of my evil biome embarks previously didn't even last one. granted, I wasn't entirely IN the evil biome this time...
