Solidarity in Death

Contrary to the location listed here, I actually found him at the graveyard of my Horde Garrison. Back by the Herb and Fishing Yards, coordinates 68, 90.

This quest is a followup to Dying Wish. After [npc=77031] dies, his ghost appears outside your Garrison and you can recruit him as a follower ([follower=208]).

After completing the first quest, for Horde with Level 3 Great Hall - You will find him in the very back of your Garrison on the left behind the Herb Garden, Just go toward your mines and turn Right on the little path to the building in the very back between your Herb Garden and Mine area, there you will find your graveyard and he is standing in it with the quest. I did this quest yesterday and came back here today and found him after reading and researching all over here for comments on where to find him. I hope this helps a lot more that have had trouble finding him. If you have a level 2 Great Hall like I did on my other toon you may find in outside your Garrison's Entrance like I did. So check both spots. He showed ups at each one on but on different toons. Good luck!
