I guess this is for Fandil, Gunther, and Sentinel. I think we enter the house. If we want to talk, we need to talk. As for the offered food - that I am hesitant about. I suspect I would refuse the food - and only pretend to drink the liquid. Then again, if they have the INTENT to poison us, I would hope Gunther could warn us of that - keep an aura out for us would you?
The 4 of us need to decide this one on our own. I'd be waiting for gunther's lead, but if he turns away - I'd encourage him towards the house.
And finally, I have never played this adventure. It is all new to me. I have no doubt that I shall walk into all of the traps - such as this one I'm now intent upon walking into...
