Morroc Ruins NPCs

[Navis]

I'm curious to know what happened to all the NPCs on the Morroc Ruins map (the map northwest of Morroc), since they're all missing. Many of the NPCs there are associated with a lot of quests, such as the Peace for Arunafeltz quest and Unlucky Emerald quests, but we can't access or proceed in the quests because the NPCs aren't there. Did they get moved somewhere else or removed for a reason? Thanks.
