An idea I had reading althistory wiki,this one
http://althistory.wikia.com/wiki/Sundered_Veil
What if THIS world would have magic?
I thought,"why not making a mod for M&B set in the Medieval world,THIS Medieval world,but with magic?".
Think of English,French,Neapolitan,Spanish,Moorish,Saracen or German knights with a sword in a hand,and a fireball in another one.It would be the most awesome things of all awesome things.
Magic can be implemented in M&B,The Gathering Storm is an excellent example.
It wouldn't be a fantasy world,though also not a realistic world.Sort of a semi-fantasy world.
It must be noted that I can't do any kind of modding for the game,but I think that I can estabilish lore,make some research and so on.
