Sooo, anyone got any ideas for the unicorn/demon problems that will inevitably spring up?
Unicorns will keep coming back, but you will never get more than 10 demons in a single fortress, and I believe that persists across reclaims.
This is a bit late, but there are 9 dead demons in the units list. That leaves only one demon still at large. The GCS squatting in the Old Fortress is a far greater problem.
From the journal of Arcvasti III, Reluctant Overseer:21st Galena:
Things are going smoothly. I've had a barracks set up in the path from the New Fortress proper to the river. Whether or not the jeweler's blatherings about invaders from the soggy depths bear fruit, its still a natural choke point at a reasonable central location of the New Fortress.
28th Galena:
The soldiers are sparring. Good. They'll need to become stronger before they can even think of facing the Giant Cave Spider or whatever horrors destroyed this place in the first place. Not all of us can be so lucky as to be granted unresisting victims like I was. Or am, I suppose. Stone doesn't put up much of a fight. Just sort of sits there. Bedrooms are intensifying and some of them even have doors now. I've been brewing up what I would call a respectable amount of liquor. It'd be nice to have a proper brewer so I could go back to mining, but whatever.
3rd Limestone:
Moony the Human III managed to get his leg bopped a good one. If it wasn't having such good results, I'd be tempted to shut down the sparring.
4th Limestone:
After only a little rest, Moony the Human III is back on his feet again. And a horse gave birth to some foals. Now that the river's properly trapped, I have the jeweler working on some way to retract the river bridge in case of invasion. Perhaps once we've moved deeper into the mountain, we can use it as a sort of moat? In any case, me and the rest of the miners are working on digging out some proper workshop spaces past the river, for once we have enough people to start working on the cloth and leather industries.
10th Limestone:
The dwarven caravan has arrived. I have everyone start hauling over trader junk from the Old Depot's location. Its a disappointingly small thing, with only a few lightly laden mules. But I guess the Mountainhomes didn't want to risk an actual caravan on the off chance that we'd survive reclaiming this nightmare.
