The Riddle of Resurrection

Another foolish individual came to me, asking the most outlandish of things. Of course, Jack never says no, simply asks for a higher price. It was this riddle I gave, leaving clues on how to undo death itself.

    My, oh my, you are in a pickle.
    Now dear old Jack shall give you a riddle.
    A loved one long lost, you hope to find.
    Your journey could last 'til the end of time.
       But is it truly her that you wish to save?
    Or rest peacefully in heaven, would she rather stay?
    Her soul is at ease, so let's not pretend,
    this act isn't selfish, a Kindred to the end.
    But still its to Jack you come to at last,
    in hopes of a way to get Anna back.
    So like Santa Clause, also dressed in Red,
    A gift I could give, or perhaps coal instead.
    But my list has been checked, more than twice,
    and more times than not you've fallen to vice.
    No presents from me, for as you can see,
    nothing worth having is given for free.
    Through the darkness where the Kindred soul,
    travels when they're bodies lie dead and cold.
    This is the place where you must walk,
    And with the king of this land you must talk.
    For only he can grant what you seek.
    But stay there too long, and your soul he shall reap.
