Now if you had said servitor id have know what you meant
ive never heard Fetchs.
I tried that once, with Torey's instructions, to my knowledge it did not work. I never tried again. I remember a girl saying she just lets hers go when she is done, but according to Torey it's dangerous to do that, they have no purpose, and can be manipulated by other stronger entities to do very bad things, (one reason I did not try again).
If I don't fully understand something, and feel comfortable with it, I wont do it.
