I'm planning on running my new players through Illumination. They're probably gonna be rank 3 by the time we start it as they're mid-way through an adventure i've written featuring a weakened Slaugth, who are going to be the main antagonists of the campaign*, infiltrator in the depths of Hive Sibellus.

Has anyone got any advice on Illumination? I've had mixed experiences with pre-written adventures, though Damned Cities is excellent IMO, and I'd like to know of any potential pitfalls.

As usual any and all advice is more than welcome.

*I'll post my campaign outline at a later time, at the moment it's a rather nebulous collection of notes and ideas though I do plan on their Inquisitor 'giving' them a Rogue Trader warrant at some point round rank 6/7.
