Hello.
There is a quest called Ancient Relics for horde, where you turn in Ulduar Relics. https://www.wowhead.com/quest=12882/ancient-relics
For some reason, I don't see this quest in the horde basecamp. I also can't find any reason as to why, there's no info on any pre-requisite quests. I have Sons of Hodir to exalted.
Does anyone have any ideas?
