Ghosts and Bleached Bones in the Ruptured Heart?

The first couple of times I walked through the Ruptured Heart I could have sworn I started seeing things. If you walk to where the zone in to Crystal Outlook is, you'll find some Bleached Bones. Now, if you hold ALT down while approaching them you'll see a name pop up and suddenly disappear. I don't know if this serves any purpose or if it's just there to mess with players but here are some screenshots:

First, here's the name of a 'ghost':


Then a split second later... it's gone:


Just another pic for the hell of it:


Anyways, anyone know if there's some quest related to these ghosts? I know there's a ghost near the north end of the Ruptured Heart who doesn't give any quests yet...

Yeah, near the south exit is a ghost who wants you to reunite his old dead caravan.

The ghost at the north end of the area is also part of a quest, get the quest from the ghost at the northeast zone entrance and then go talk to him.

I first noticed this in Factions with the mobs that drop out of nowhere.

I think is has something to do with the npc/mobs having to be there in order to be activated, by quest or conditions like passing by, etc.

Also If you've noticed, the distance you see objects, npc's, and mobs with the ctrl and alt keys is slightly farther than the radar, I believe this also has something to do with the 'disappearing' npc/mob/object. When you first some within ctrl alt range the object is initialized, during which you see it, once fully started its properties are invisible, so you don't see it, as this is probably a one time initialization you don't see it again unless you rezone.

If all objects were initialized on entering a zone I would imagine a problem with speed would crop up.

A-net could probably eliminate this issue by making the ctrl alt only see as far as the radar.
