On the 14th the great gates will open, the doubts thou hath will be cast away and only the light of the Demigods will remain. Your inactive key, gift earned, will burn brightly and blaze with power.. Then, and only then, will you know to which lock it belongs and thus be given the chance to wield it.
So, I'm bored here at work. Slow day. Yes, basically it'll change on the 14th.
EDIT: Darn, someone beat me to it.
