I plan in my very first Edge session:
1) the PCs bump into a disgruntled human talking to a Wookie about debt to Jabba as they exit Jabba's town house etc
2) Jabba surrounded by all his goons including a guy dressed head to toe in Mando armour.... talking to a Rodian....
3) an aging human berating a teenager about the current state of their droids, moaning about meeting his mates at Tosche Station...
4) a certain bartender yelling at the droids to leave, if I have any droid players
because once they start zipping around the galaxy there's little chance of them bumping into the iconic characters....except Vader and the occasional Inquisitor
