[MsAligned]

cleared the map, after the last one, 2 lines of text from the Void Harbinger: 

Void Harbinger: We no longer serve your mistress. Lights shine in the black. Salvation approaches.
Void Harbinger: We cannot speak here. The Mistress' net is cast. Find me with my kin.

 

mission objective now shows ??? no idea what that means.  went back to Wayward Warshade, cannot target her so cannot talk to her, nothing else is on the map.  30 minutes later she disappears, this text NPC  Duskbeam, Wayward Warshade: If Slag Heap is here, then she can't be too far behind...

and the mission ends
