A migrant wave just arrived for me, and I decided to see if I could get ANY of them inside before the zombie horde tore them to shreds.
I admit to savescumming on this so I could see just what was or was not possible with the defensive setup and military force I had on hand. On my 3rd attempt, I got one migrant in who ran through the crowd before I decided I had to shut the gates. Unfortunately I decided this too late, and there were too many undead, one of them a were-bull zombie who punched the spine of a dwarf through their armor.
On the next attempt I was a little bit luckier. I ordered all migrants into a squad (thanks, dwarf therapist!) and ordered them to run into the fortress. 3 got within sight of the hole before the horde descended on them, and even going into a martial trance was not enough to save one mighty warrior. Of that lot, one migrant again managed to slip past the undead and make it safely into my fort. The same one as last time: Fath Oslanmorul, a promising metalcrafter! I decided to check DT to see just how agile this nimble dwarf must be. What I found was that Fath didn't exist. A metalcrafter by a different name was the last surviving member of the Migrant Squad. How odd. Wheels started turning in my head: Same migrant both times...errors in DT's name display...able to pass by zombies unscathed...and, just to be sure, this dwarf has been a member of 5 different towns.
Yep, I have a vampire in my fort.
(How much "fun" I would have been in for had DT not shown me too much info? Vampires in zombie-land. What sort of fun should I get up to with this guy?)
