here's an idea. To get on with new (and old) members creative sides I suggest a number of topics (after this) on historical events in the TW games. As in a Crusades one (this one), a Punic (carthage vs. Rome) one, a unification of Britain one, etc. the story starts in 1 week real time.

Here are the characters (and what they do):-
Pope: starts off story and gives updates every week
King of France, King of England, Emperor of Germany (HRE), King of Spain and King of Sicily: Kings of crusading nations, can go with army(suggested) or sty in country and be the deep philosophical part of the story
King of Egypt, King of Turkey: leaders of nations resisting crusades, almost definitely fighting against them with there armies
Byzantium Emperor: most interesting position as he can either help crusaders or refuse them passage, he should be aware as Crusaders aren’t the most disciplined when it comes to not attacking rich cities like Constantinople
Soldiers in French, English, German, Spanish and Sicilian armies: any person can come in at any time and do a blog/commentary on the battles or anything else
Soldiers in Turkish and Egyptian armies: held firm by your belief in Allah, you…. Just do exactly the same as the soldiers in the crusading armies but from the defenders army

Also: Head of army if King stays home
