...perhaps somebody let a tweaked adventurer loose onto the map before I got there?
Super new super fresh world, only year 60 when the megabeast counter kicked over, so I jumped right in, I'm having fun, trying the soft cap/hard cap 30/no babies start for a chance (which is nice, not rushing to dig out hasty bedrooms for 50 dorfs suddenly) and this guy shows up.
Now, yes, that's the dfhack manipulator interface, and I was making use of the armoks blessing script once I get new arrivals moved in, because I just didn't care to mess with skilling stuff up instead of playing around with the extra time I had available to do other stuff, so anyway, I like to set up civilian uniforms to keep clothes rotting away from being a problem (leather armor/leggings/high boots set to replace clothing once and then let them wear it over clothes and they're happy as any congregation of hairy leatherbound drunks should be) and I was using the visual indicator of "who didn't have a row of z's in their skill lists" to make sure things got equipped right.
Then this guy pops up, still tagged as a new arrival, hadn't even gotten the bedrooms assigned yet, and I'm like "oh, well he's a vampire, obviously" so I isolate him and keep tabs while I work on other stuff.
*sees him flashing the thirsty/hungry arrows*

He eats, he drinks, nobody has gone missing or been found drained in the almost year since he got here, I changed his name because it was "Urist McVampy, Obvious Vampire" until it turned out he was just that awesome and I misjudged him?
Is this a thing now? Random 20 year old dorfs with maxed skills/stats and surprisingly well-adjusted personalities show up on your doorstep?
