Hi guys, I'm into the third year of my first fortress and have a couple of questions. Things are going fairly smoothly, but I neglected my military for some time. I have 15 melee troops and 10 marksdwarves at the moment, but basically none of the melee troops have any weapon skills. They're training so I presume that will improve over time, but:
1) I just had a forgotten beast spawn in the cavern below me. It's a giant tortoise with fire breath, and I don't think any other special skills. Given the state of my military, how much fun will I have trying to kill it? I'm pretty sure it can't get into my fortress (a mining shaft breached the cavern, which I've since put a floor over so there should be no way in) so should I wait for my military to improve before trying to take it out? If so, how long should I wait (i.e. what criteria should I use to decide when to go for it)? I was planning on exploring and sanitizing the cavern fairly soon, but I'm thinking now I need to delay.
2) I have a population of around 60 dwarves (plus 12 babies) and something like 500k in created wealth. But I still have no mayor (just expedition leader), or other higher ranking nobles (an emissary just left and didn't offer a barony or anything). I know these nobles have specific room requirements--do I need to build the rooms before I can get them? And if not, why don't I have them yet?
