Party got TPK'd
The party made it all the way to ghenemal without being discovered until she saw right through their forgeries. Totally unable to deal with her mighty prowess they tried to escape only to be cut down by the guards.

Party: Gnome wizard, Half orc inquisitor, rat folk alchemist and a human gunslinger
