Speak with Mog'dorg

Part of the quest chain to open up the Ogri'la daily quests. You have to kill five different elite Sons of Gruul. They are VERY tough and you must have a proper 5-man party to handle them (Tank, Healer, 3 DPS). You might even want to bring along some extra people that can help out of party.

Quest Chain:
Speak with the Ogre
... Mog'dorg the Wizened
...... Grulloc Has Two Skulls (Grulloc)
...... Maggoc's Treasure Chest (Maggoc)
...... Even Gronn Have Standards (Slaag)
......... Grim(oire) Business (Vim'gol the Vile)
............ Into the Soulgrinder (Skulloc Soulgrinder)
.............. Speak with Mog'dorg

Couple of notes, if you are trying to do this for quest completionist purposes.

1) Wowhead has it noted as a Night Elf quest. This is incorrect. I was able to do it on my Lightforged Draenei, and I'm pretty sure it's available for any race.

2) It is a breadcrumb and acts like all breadcrumbs do. You want to make sure you complete Into the Soulgrinder, but not the followup. Instead go down the tower and move along the Supplicants. This breadcrumb quest did not show up immediately for some reason, but after about a minute I found it: https://i.gyazo.com/985b40f95ed78da993949a4b8633443f.jpg

They respond to emotes when you turn king/queen!
So far they respond to /kiss, /point, /dance, /laugh and /roar.
Really amusing :D
