There is a test version of the war system, which you can try out via the cheat book in your bedroom in the castle of Aldlyn. The system will probably get expanded and changed once it'll get included into the game, but the test version gives a first look into some of the systems and plans for it.
Thank you for the praise. I'm happy that you like my game. :)
I'm hoping the get one more update done this year, and I'm aiming for a release between Christmas and New Years Eve. However, due to the holidays, family visiting, and all of that stuff, I can't say for certain when the release will be.
