Do you know of the being he is talking about? Seems like a sticky situation to say the least. Do it and the devil holds a hand over God, don't and you won't get Jacek back.

Althoughhhh I wonder if you can get this creature to help you get Jacek back from the devil. Maybe the creature can fight the devil? Food for thought. Get Jacek back by force, don't let the devil eat the creature.

How are you doing without Jacek, by the way?
