I don't know about Wraiths and Reapers but I would love to see other entities in the game such as Ghosts or Spirits that might come out after dark from time to time or even Sprites floating around in the darker wooded areas. I think it would be fantastic if you happen upon these while exploring or just traveling in the less inhabited parts of the maps. It would certainly add to the atmosphere and they don't even have to be interactive, though that would be nice too.

What if certain areas were more or less 'spiritually attuned' and you'd occasionally see glimpses of unidentifiable players spirit walking? That'd be pretty eerie. Since I believe NPCs don't have souls in Elyria, this is the best way I can think of that being incorporated.
Could be non interactive for the masses but maybe the rare few talented players could somehow affect these wandering souls?
It may be interesting to make such spooky places a challenge for getting back to your body - avoid the deep woods on your way back to your body or you may end up trapped in the spirit realm/astral plane forever.... - or something like that. Or there could be an equivalent where you WANT to go through the woods on your way back because the spiritual energy there makes you move quicker (there would be cause for more spirits to be passing through that area if this were the case, so more ghosts sightings?)

To add on to Slaine's idea, some manner of spirits are merely an energy print that plays out an event over and over again. So meeting certain criteria, what if there were areas where these energy prints could be made. And at certain hours during the day or night, weather providing (like overcast during the day for example), those energy prints play their events and perhaps startle anyone not expecting it.
