Three players, three games, one campaign...

I want to steal/borrow/modify/design some scenarios for the upcoming weekend.  The game will be using the wonderful Song of Blades and Heroes rules, from Ganesha Games.  My wants list, my ideas:

• All three players must be able to play each game at the same time, with equal forces, without a simplistic victory condition like: 'winner manages to wipe the most models off the table'...

I think the best way to do this will be to use objectives, markers that can be found on the field, that may or may not (on the roll of the dice) be what the player is looking for, or hoping to find.  It may be items, it may be money, it may be something else.  But there should be more than one real objective, and each 'real objective' should be something the player can use or that will benefit the player going into the next game.  

• The three games should have some form of story arc, or be a precursor (set the scene) to a set of linked scenarios that do.  

Either these scenarios follow a story, or set the scene for a future story.  Given the time constraint I'm wondering whether the latter might be easier to accomplish, and allow for the three players (and the scenario designer) to ease into the game.

So, has anyone got any suggestions for where I might find such scenario ideas, interesting ideas, what to avoid or what might just work...

Thanks for any and all advice...

Oh - and this is a rough map of the area in which the games will take place... why? I'm not sure yet - maybe over several campaigns we'll find out...

Cheers,

Giles.
