Wow, this concept is certainly exploding!
Dark Magic is a good option for the GLADE team, but I'm really not sure on a final tech tree diagram as of yet. Since that is my job, I will get on it!
I was hoping that the GLADE team would extend Magitech first, because that would be coolest, but that can just be the second project we work on. I thought it would be a good option because a lot of the work is already done, like the music, and some unit ideas, etc. But Dark Magic is definitely great too!
And when I said that you should contact the head of each sub-department, I meant that if you want to animate, you should contact the animations artist. But more communication is always better than less!
