Spirits in Shadowrun. In the rules it seems like spirits are called from elsewhere and they have their own lives etc. But there are watcher spirits and Ally spirits. I'm a little fuzzy on watcher spirits but Ally spirits, because they have a formula, they seem like they seem like they are created by the mage. Are they created or does a pre-existing entity with a life and experiences show up if they fulfill the menu points the mage has set out in the formula? Do mages essentially create a magical A.I. or does some entity show up with pre existing conditions and baggage and the mage and spirit are forced to love one another all rapey like, warts and all (providing the GM with plenty of story telling dysfunction to draw upon)?
Man, I gotta add 15 and 15 for the captcha?!?!?! That's discriminating against orks and trolls!
