miss nerissa would be the better candidate for that question, but if i should offer my own interpretation of what she is speaking of here...
a teleportation spell is a very simple one to those of this world. the amount of energy consumed - the 'price' - varies depending upon how far one wishes to travel, but it seems to be among the basics taught to new witches.
i would say to imagine our transport here as a sort of teleportation spell, one on such a grand scale that it cannot possibly be paid for by one witch. so the entity casting the spell reaches for the 'animal blood' so to speak - the burden of the price is placed upon something, or someone, else. the ability to use this world's magic is not what those of us turned into witches gained in exchange for our native powers; it is our transport to this realm in the first place.
