"All in good time, my dear..." teased the voice.
"So, what the hell are you and what gives you the right to invade my body..?" posed Rachel.
"Honestly, nothing gives me such a 'right', as you put it. I simply 'choose' to do it. I am, as some may describe me, a Djinn - a form of Genie - but don't go getting any ideas about wishes or anything. I'm long past that meagre stuff. I was released many millennia ago from the shackles of those rules, but I retained my powers and was imprisoned in a piece of black silk by an other powerful being. Throughout the millenia, this fabric has been passed around, and re-used, splitting my being into many garments and items, using humans as a means of passage." extolled the voice.
"And where do I fit into this grand scheme?" added Rachel... "Am I just a 'means of passage' too?"
"No my dear, you are something more... " postured the voice "As i've become more and more fragmented, my powers have weakened. It's now time for me to take action and rebuild myself! You, Rachel, will be key in this process. My powers over the body and mind will allow you to serve as my key tool in my endeavour!"
"Tool?!" spat Rachel, forgetting her place "I don't want to be anybodies tool!"
