The response is quick, almost instant, but at the same time it is not sudden. There is no sense of urgency, or any confusion, every part of the process is delicate, controlled, considerate, and clear to her. Information flows, almost physically as if up her finger, arm, shoulder, and neck, and a whole realm of knowledge enters her.
The Needles are indeed an artifact and a person. They possess great powers to heal, but also to encourage growth, to refine and improve upon life and living things, most especially things of a human nature. They possess a great deal of information, drawn from countless wielders spread across countless worlds. They possess a powerful, inherent drive to utilize their resources to aid others, to bring about healing and happiness and fulfillment and greatness and many other particulars. They cannot wield themselves, however. Another must attune to them.
Feli has not attuned to them, the process is metaphysically impossible without the wielder first being fully aware of the power and the nature of the needles, and once so aware must initiate the process. Feli is now aware, and now knows how to attune, if she so chooses.
This all has settled into her mind, almost as if she'd always known it and only now just remembered it, in no more than a single second of time.
