My last four characters went with Kymon because it suited their builds but with my current Witch Hunter, I went with Order of Death’s Vigil. Since I was used to the whole Empyrion quest-line which explained a lot of lore, I was expecting something similar with Death’s Vigil. What I got, was a crappy resurrection of a death knight that doesn’t do anything and a quick trip to the East Marsh only to find… nothing but the Skeletal Monstrosity. Did I miss something back at Necromancy HQ or is that it for their quests? I spoke to everyone and even went back to where we resurrected the death knight (can’t remember his name) but I couldn’t find anything else.
Nope, that’s it. 
It’s just another one of the many unresolved quest lines in the game. I’m really hoping they each receive some kind of resolution quest in an expansion at some point. I know the main quest will, obviously, but hopefully the Kymon/Death Vigil quest lines will be fleshed out and concluded as well.
That’s extremely unsatisfying. I did this quest line back when they first introduced the two factions and I was certain Crate would have expanded upon this faction a bit more. Instead, they just added a worthless trip into an area and left everything past that blank.
I think more stuff will come soon, there is a “pledge to cairn” quest set up for probably revered rep on either faction
Both Malkadar and Barthollem end up meh after all that set up
I was expecting to see the faction summon help me out in some way, but no, they just sit there being useless. It would be nice if we saw them used for a quest-line later, but it just seems lackluster for a final release.
