There's a possibility of a brief intro session on Psionics/ToB/Incarnum once more. I'm available right now (Maptools b76, server name AltEnergy password admin) for an out-of-character encounter.
Edit: Bugger that. However, for a mini-campaign (well, probably mini), I have come up with a somewhat reasonable hook for a random assortment of characters to come together without starting in a tavern:
In the city of Villageton, there is plenty of merchanting to be done. Some of this includes merchanting in other towns. So, with a promised reward of ten thousand gold (split among whoever is hired; and loot if bandits attack and are killed does not count for this ten thousand), and your characters being the first to sign up, adventure awaits! You will meet at the north gate with your employer, a dwarf bringing the metalcrafts of his clan to the town. You will travel north to the Cold Mountains, where your employer brings his wares to the legendary Fort Citadel. The first stop will be the village of Empire, a two week ride north by northwest, from where the legendary Emperor King singlehandedly captured half the continent before succumbing to the common cold; his son, the now-Emperor Prince, was a bumbling fool who lost all of it but the village that now bears the name Empire. ((Free Knowledge checks, away! Actually, the Dwarf has an archaologist (Idaho Bones) with him who has lots of knowledge ranks))
