Well to start I spent a few hours playing with advanced world gen to get a world I liked, and I chose a site on a sinister swamp (indadvertently next to a good swamp) that has humans, dwarves, goblins, and 3 necromancer towers nearby. So yeah, I purposefully embarked near them, just so there is a bit more interesting things happening at once.
The evil side of the map constantly rains elven blood, which is odd because this world has never seen an elf before (no good forests generated), and likes to send undead ravens and buzzards at my fort constantly.
Currently under siege by all three towers, one tower has access to these execrable mist zombies, covered in the mist that zombified them, the other two towers seems to just send generic undead. Its getting a little out of hand, since the goblins and kobolds keep sending ambush squads that get detected and torn to shreds by the roaming horde of zombies. The necromancers seem to have left for now, unfortunately. I want to catch one or more for some little projects I've been wanting to try.
Working on getting armor and bolts made for the civilian population (we are holding steady at 27, pop cap is set to 15, with 10 children allowed), with 4 full time hammerdwarves clad in home-forged steel. Copper and gold are abundant as well, and since I brought 100 bitumnous coal with me I've got coke coming out of my ears. Got a few crossbows forged already, just waiting on armor to protect the fleshy bits of my dwarves before they climb on top of the makeshift roof and rain down bolts of vengeance on the undead.
