Precursor and prologue for SCAP

[Luciano Thrice-Damned]

I am going to be moving soon and will be trying to start up a SCAP campaign. What I was thing though is that I will want to run a short (2-3 level) game first in order to a: introduce the players to Cerilia, the setting I am using (the old Birthright setting), and b: help the players get to know my GMing style and me to know the players before I launch into my grand campaign.
So I was trying to decide on a good adventure to run that would allow me to foreshadow some things from SCAP without giving away too many spoilers. It should be noted that I am using the Alternate Cagewrights and most of the foreshadowing ideas that Delvesdeep wrote up (as they are great).
So does anybody have any good suggestions?

If they wont be the same characters used in the AP you could have them play as Striders of Farlanghn and then replace Fellio, Shensen et al with those PCs

Wow! What an awesome idea, Coridan!
I second what Coridan said. Anything else I might have suggested could not be that sweet.
