Converting the Unusual Experiences tables in Reign for the Forgotten Realms setting. I tended to use these to link PC's to Companies, which could be a huge mistake. If you end up linked to a Company that you don't want to have an affiliation with for the campaign you are playing, just say that your link to that company was in your past, fun color and spice and a reason to cross paths with the Red Wizards of Thay or the Harpers in future games.
