So I know GMs here tend to dislike sticking to 'the books' entirely, but since I've never actually run an RT game using them, I thought 'what the heck, I've got half a group of people virigin to the 40k setting, might as well just use the adventure books!'

So my question is, before tossing in a custom endevor where I strand my players above the witch-cursed world, is there already an offical FF-written adventure written for that setting?

Sorry to say mate, but no official FFG written adventures have been created for the Witch-Cursed World. However, in the core RT book page 342, and Edge of the Abyss (EotA) page 26, are some information about it.

As for written adventures, please refer to the link below to get more details about it.

Nah that works for me, I've gotten something written up for it already, I just wanted to make sure that I wouldn't be about to break my experiment.
