Classic baby-left-at-doorstep scenario.
Raise her to be a cliche super hero.
Totally! The position of Champion is currently taken, but perhaps when she is all grown up, I can keep the slot for her. I'm trying to decide what to nickname her: Megamind comes to mind, at this point, but I had been thinking of another emancipated baby I had years ago, who crawled to me fort instead of travelling by womb. His name was Demoncrawled, I kid you not, and I felt he was pretty awesome. Then he enticed a werelizard into the traps and "killed" it, and the baby Demoncrawled became a wonderful legend to me.
For your confusion, the others are suggesting the ordinary "do something really awful to your useless dwarves for fun" attitude. Such as killing the baby because that's how people work here.
I seeee. Well, I do that too, to useless dwarves. However, she's interesting, and seeing as the entire purpose of the game is to be interesting, I see no reason to smash her, she is fulfilling a purpose.
I think babies should drink water if they are abandoned so you need others to give them water like in a hospital.
A non-issue for me, I have enough booze for my fort to not need a brewer for years. But yes, I guess if I hadn't stockpiled up the booze and fruit for more booze and yet more booze (and stone pots) then I would be checking who "needs" booze and who doesn't.
