A wasting corpse visited my fortress. That is to say, an undead human crossbowwoman named Udal Curotosi (Ringrace) showed up.
According to Legends mode, she spent her living days as an unremarkable soldier and monster hunter, occasionally being a fisher or herbalist, married a somewhat renowned author who went on to become a baron after they divorced, then got into less interesting romances three times later
At the age of fifty, she got into a fight with a minotaur and survived unscathed.
At the age of one hundred, this woman went out to kill a night creature's consort listed as her sole kill.
And at the age of one hundred and eight, she picked a losing fight with a giant.
The giant seems to have been mostly a petty thief and vandal, as far as giant-scale crimes can be called such.
152 years after her death, a passing necromancer brought her back to (un-)life, in whose service she now is. That necromancer is not exactly the brightest, apparently, because he sent her to arrange a coup in my fortress and steal artifacts, but all her character traits suggest she's useless at subterfuge or deception.
She's dutiful but can't handle the pressure of it. She loves making friends but is quick to pick fights with people too. She doesn't envy others and can empathize with their worries. Loves art but sucks at making it.
And the entire time she was in my fortress, she was in my tavern, presumably partaking of dwarven wines and meals instead of actually engaging in the kind of villainous skulduggery that she was sent to do. She came and went and did nothing of note whatsoever. I do hope it stays that way; just go and enjoy your second lease on life, Udal.
I know it's nothing special as far as visitors are concerned, but it struck me again just how colorful the lives of random passers-by can be in Dwarf Fortress.
