Okay so I've got a group of rebellion special operators going to be making their way to Coruscant to retrieve a VIP. What sort of trials and tribulations should I have them face to get there and to get out? I've been rather lax on customs and inspections in the past but those worlds/encounters weren't the capital of the Empire. The group itself is very well experienced and have a few contribution ranks under their belt. None of them have been directly identified by the Empire as they work as spies or special operations troops most of the time.

I'm thinking of adding setbacks on their rolls to bluff their way past any officials that matches their contribution ranks at least on the initial entry and when faced with someone that might be in the know of such matters. In game time it is around 6 months or so prior to the battle of Hoth. They've fought and defeated inquisitors before as well but I'm trying to keep them out of this bit of the adventure and keep them for more big ticket scenes later on.

I've done some reading on wookiepedia but I figured some advice from you mates wouldn't be a bad thing to ask for.

Have you read Dark Horse Comics last Star Wars comic series dealing with the main trio and not the Rebel Heist series?

Han Solo did this but it turned out to be an ambush which Han managed to escape making a new friend and smuggler ally for the Rebel Alliance.

No matter what your players do the Empire will know they're there I'd use any successes they gain on the way in as bonus dice they can save to use whilst on or escaping Coruscant.

It should be difficult but remember if they're rookies the imps will be watching them in hopes they reveal their contacts or lead them to someone(s) much more important!

Give it a couple of setback dice on the way in and 4 or more on the way out to demonstrate just how dangerous it is that's why those saved bonus dice earned on the way in will come in very useful!
