After finding and closing a second shadow path I fight someone I'd killed earlier https://redcircle.com/shows/bd535987-8b1f-4ba5-afcb-adb2484eef24/ep/edf7fd10-92b7-4850-8298-8633466a6b39 the second try doesn't work any better.
I then learn of and play a part in, the tragic fate of the mage Nillom who give me what I need to strike at the heart of this business.
