Unfortunately i didn't save the world map location, but i do have the local map. It's a 6 x 6 embark with a magma pipe, bottomless pit, undergruond river, chasm and HFS.
Just as a note; i'm using the latest Mayday version with Orc mod and Beefmo's graphics. I've also custom modded in a number of new critters and Hobgoblins as a new civ (i can't remember all the changes i've made, whenever i get bored i add something random) so i have no clue if the world will gen correctly or not.
As for finding skeletal\zombie GCS; just mod them to increase their frequency (bigger cluster sizes, reproduce faster) and then embark on evil mountains with chasms\bottomless pits. You might have to try a few diff sites, but you should find some eventually.
