Use this at your own risk, this changes a LOT of different aspects of the source code and I am NOT going to take responsibility if you break your upgrade path!
A future version of Intersect may or may not get an official Faction system, so don't say I didn't warn you.
there's also no guarantee this will work on your build as it was written against an in-development version of Intersect, you may need to fix conflicts yourself as I am not going to keep updating this every other day.
Descriptions: A basic feature of faction system. You can do your game between faction pvp !
Note: You should choose faction for pvp. If player don't have a faction server giving error.
Thanks to @Cheshire. I'm using her Guild System source.
Lets Enjoy !
