After a couple of rather successful fortresses that I had to discard before the economy kicked in, I'm now starting from scratch. It's late winter in the first year, and I managed to fill my reserves of food with just one fisherdwarf and proficient grower working full-time. It's amazing what a bit of skill can do to keep a fortress alive.
I've managed to build a pair of copper cages for my mules and horses, who had given birth to foals prior to being caged. Do they still breed in captivity, or do I have to free them and design an indoor stable for their use? I really want to keep them far, far from the wilderness, as massive herds of elephants tend to prowl just beyond the river.
I'm also planning to create a military once I hit 30 people. Preferably marksdwarves, so they'll later have a small chance of taking down elephants. Do they only train with wooden bolts? And how exactly would I need to set up the barracks? I notice I can give both weapon racks and armor stands "barracks/armory" status, so I'm not sure whether all racks in the same enclosed space ought to be assigned as rooms, or whether I should just assign one of them... Or none at all.
For that matter, how does the game react to multiple rooms overlapping, assuming they're of different kinds (i.e. a dining room, study and bedroom)?
Finally, I'm curious how siege engines work. What do I stand to gain from building them? Do they work indoors? Could they, for instance, fire straight into a herd of elephants?
