Started on an evil region, successfully cordoned off the embark wagon. No undead wildlife sightings yet. Aquifer breach successful, though it cost me a miner. Farms are taking up nicely, now to carve some room for workshops and stockpiles.
Outside, it's raining stinking muck that makes people nauseated but seems otherwise harmless. Also, some migrants seem to have decided to settle in Battlestandard. I pity the fools...
Welp, that was quick. An hour or two real time after posting the above, everybody at Battlestandard had gone murderously insane from being forced to sleep on the ground and drink slime and/or vomit. Technically the fort didn't crumble, since there was a berserk and a lunatic still alive when I abandoned.
Not to be so quickly dissuaded, I genned a new world and did another evil embark that is currently in the process of carving out space for workshops, the main dining hall, and jails. The evil weather
du jour is a rain of red goo that induces a slight fever. (The vomit-inducing muck was green; I wonder if there's a connection between the colour and effects of evil rain?) Still no sightings of undead wildlife. That is wont to change at a moment's notice though, because there seemed to be a necro tower nearby...
Now it's a race against time to get up a well running off cavern water before thirst becomes an issue again and some sort of perimeter defence before the necromancers come calling.
I think my main goal for now shall be taming some of the lovely cavern creatures around here.
