I tried out site building and just as I feared I'm occupied in fastidious pointlessness like singling out larch trees for the exterior. I have a temporary tavern zone under a temporary shelter with barrels of booze, a chest of cups and a chest with one instrument. Because I'm using advfort for the structure, my companions are all bullshitting around while I do all the work, but I've learned a few new forms and works from it.
I've got the beginnings of a longhouse mead hall, about 460 square units area, on a raised basalt block foundation. I'm not far from a beach shore with tides creeping in, so I have to hurry to get a floor on it to move the tavern up. I plan on a paved obsidian central floor for the tavern area, and a pine wood floor around that will be zoned for the main hall. I also struck a gold vein in the obsidian, but no idea yet what I will do with it. It's so heavy and has to be carried 10 zlvls up, so I'm reluctant to rely on it heavily.
EDIT: A crash brought me back to my senses; this was only supposed to be a temporary base to raid the Dark Fortress 1 world tile south. But maybe after I'm done they'll come visit the tavern for R&R. I think 'The Rancorous Forks of Horror' would be the kind of beach and leisure resort demon thralls would enjoy.
I left the deadweights behind because I knew I couldn't trust them on an infiltration mission and slunked into Ruthlesscradle by light of the full moon. Mothers all over my civ have cried about their abducted children being taken here, but cell after cell was empty. If I had to count I would say the total human population here was me. Of the many times I've attempted this mission, not once has it ever gone remotely as described! Whoever claims to have rescued children must be either full of shit or playing a different game!
Since the mission was a scrub and they didn't have any loot worth sifting through, I left them my calling card: an assassinated lord and 44 skinned beakdogs.
