Hi, the quest from the Grotesque Remains in Val’sharah, part of the Lostlight Grotto achievement for Sojourner of Val’sharah, is not completing for me. I’m unable to pick it up, it appears as a ! on my map, and I’ve already completed the following quests. Thanks 
same issue, cannot find the quest
did you get to finish it yet ?
It’s a quest item drop from the mobs there
Just keep killing mobs until it drop, you probably forgot to loot stuff because it’s kinda a waste a item unless it’s empowered mob or rares.
Just found the quset after we kill the mobs in the cave downstairs. it is not a loot cheest at original
