Servant in the Graveyard?

So I was doing my dailies, specifically the kryta vista viewer, and picked the vista in the graveyard. Approaching it I noticed something odd: A servant was crying in the building at the centre of the graveyard. I hovered over and noticed I could speak to them, so I went to get a closer look... except they vanished in smoke when I got too close. I sadly didn't take any screenshots and have been unable to replicate the situation.

Does anyone know anything about this? Is it new?

Edit: A little digging and it's something that was in the default game, a flavour npc by the looks of it. Don't mind me :D

Even if it is since launch, if we don't know who it is then it's worth wondering about
