I am by no means a real modder.  However, I was playing around with the professions and was able to tweak some values.  I’ve included the part of the mod that you can use to get a “Spider Worshipper” profession (inspired from a fantasy novel series…hehe).  The name is just a placeholder until I think of something better.  Basically, rather than Sentinel units, you will start with three black widow spiders.

Copy the below text into your “SovereignHistories” directory.  It worked for me and was a cool effect.  I believe there is some place to make a copy of the mod directory, however, I just edited the default file.  I don’t actually know where in the mod folder I’d place the file, hence, I changed the default file.  If you mess around with this, you can change the spider types too.  Enjoy!
