My group is chasing a rogue Tech Priest who stole Xeno Tech from his inquisitor master and left his master for dead. My group, acolytes to a different inquisitor are tasked with tracking down this tech priest. The group has worked out that the Priest has had dealing with a business man, the thing is I want the business man to be the leader of a secret Slaaneshi cult. |The problem I'm having is how do I draw subtle attention to the fact he may be a cultist? I though about having vile painting on the wall showing forms of sexual torture and stuff painted in equally vile colours. My group are only just into rank 3 and as far as I know none have the ability to spot a cultist straight out. Another way I thought of drawing attention to the fact he's a cultlist is for him to offer the group some form of hallucinogen that will result in them seeing Daemonettes and basically a bad trip that will make them suspicious.
The fact he's a cultist has no real baring on the campaign itself. I want to give them a small side quest to hold them up for a session or two whilst I work out where to go from here as they managed to wonder so far from the path I was trying to guide them down.
Im just not sure how to get my group to uncover this minor cult so that they can shut it down.
