Iron Gods: Beating "Father"

It's been a few weeks since the last one so I can't remember all of the details.  I know they took out the robots in the last room and then decided to go and chase down some information on their friendly neighbourhood drug dealing merchant whom they are damn sure is a Technic League spy.  Our lovely tiefling seduces him and the others (plus Cleric of Brigh as a witness) rock up to interrogate him under a spell that prevents him from lying.

Sanvil Trett deflects their questions for awhile before finally drawing his sword … and being soundly beaten and grappled.  Then he finally admits that he is a Technic League spy, but he's willing to defect so long as he can investigate the ruins once they're done.  They accept this possibility but keep him under house arrest at the Evercandle Inn for awhile as they go off to get a broken elevator part repaired (which takes a couple days due to bad rolls).

Once they have the part repaired, they decide to follow up on a lead given by their newfound "friend" into certain strange activities at a particular warehouse run by Garmen Ulreth.  While approaching the warehouse, they start getting headaches.  Going inside they find a couple thugs and having decided that punishing the previous thug left them with a bad taste in their mouth, they went non-lethal.

All except for Nathaniel who decides to go for the kill.

When the thugs press their attack, they manage to bolt the door on Nathaniel who stealths away and around the building, brooding.  The others manage to get inside and head into the office to try and intimidate Garmen Ulreth who's sitting in his makeshift office.  In the end, when Luna tries to open the wrong thing (or rather, the right thing), Garmen calls in his guards and attack.

Luna keeps the various doors shut and bolted while Garmen tries to get his troops in, and they kill Garmen Ulreth.  Once their boss is dead, they open the door and use his corpse as a reminder that the thugs should run.  Which they do.  Promptly.

They find a strange device in the warehouse but they don't yet know what it does.

And that's where we left them.
