First, some backstory - the original GoMs were not my creation, but Minisauron's. In stark contrast to my own habits (where I make multiple breeds), Minisauron took a single breed and refined it over the course of many years and in-game generations. The ultimate result were the Arimeides Grendels of Minimordor, and later on the Ueber-GoMs (who are more of an update to the Arimeides). If you haven't tried out either of these, you should - they're an absolutely amazing breed, and a very unique one at that. Both the Arimeides and the Ueber-GoMs are available at Minisauron's section at the Norn Adoption Center, the Mini-Blackgate.
Now, onto my own GoM variant. For a while before making these, I was scrounging about trying to either find a breed to use for a wolfling run or trying to come up with an idea for my own. Eventually, I settled on the Ueber-GoMs, as they are one of my favorite genetic breeds. They worked for the world I set up for them, but I couldn't help but notice how stupid and idiotic the males were - in a few generations time, they were outnumbered by the females, with a breeding script that strongly favored male eggs.
Since the Uebers didn't work out as well as I hoped, I decided to make my own variant. I originally wanted to base their genome on the Ueber genome, but Ueber brains crash the genetics kit, and I've yet to find another genetics editor that can even open their genome. So instead, I went back a breed and based them on the Arimeides, where I came up with the name and backstory for them....
The word "Facticius" means "Artificial" or "Man-made" in Latin, which reflects upon these GoMs' history of being artificially enhanced as opposed to (mostly) naturally bred like the Ueber-GoMs were (a history also reflected by their alternate name: The Forged). They share many features both with the Arimeides and the Ueber-GoMs, but also bring a new set of features to the GoM gene pool (most notably Vampess's CFE edits).
I tried contacting Minisauron about this new variant and seeing what he thought of them, but unfortunately the e-mail address I had for him was apparently defunct, and the only other way to get a hold of him was through DS (which is no longer a viable option since the server's been down for practically a year). However, the readmes for his GoMs said he didn't mind people distributing or modifying the packs...so I'm hoping he won't mind me releasing an edited variant of them.
