If there's something out there that wants you, for whatever sick purpose it can fashion, Eon, I'd figure that to be an evil thing.
Spirits don't like us physical things, for some reason. Angels don't mess with us save on God's commands, and they're here as messenger boys, nothing else. They're not here to fly aruond and guard you from cars or falling meteors or dust bunnies. They're here on a "mission from Ghaad" as said in Dan Aykroyd voice.
What are the Eldritch forces? I do not know the name. Also, see, I don't think humans ever USE a spirit...they use us. We can talk to them, get info from them, use them for menial tasks, but in the end, it's them pawning us around. Which is why it's not smart to mess with spirits or mediums or necromancers. They all exist, and they work, some of them, but the end result still isn't pretty.
One of these days, I would love to find some kind of division of the Church that investigates the occult, and I would love to enter into something like that. The occult fascinates me, but what tends to keep me out of trouble with it is that I know when it's insanely dangerous to be dabbling with.
Magic has insanely great art on its cards, and of course, there are summonings, magical artifacts, monsters, zombies, warriors, valkyries, ghosts, demons, golems and much more pawns of the players to use in the game. What you do, like what you do with D&D or anything else where the player enters a "kingship" state of mind is how you perceive it...game or not?
And PureFun, what the freak is "you'll surely burn" all about?
