Answer:
A morbidly-named body of water
When there is fire in me then I am still cold. When I own your true love’s face then you will not see me. To all things I give no more than I am given. In time I may have all things, and yet I can keep nothing.
Almost everyone needs it, asks for it, gives it. But almost nobody takes it.
In your fire you hear me scream, creaking and whining, yet I am dead before you lay me in your hearth.
Thirty white horses on a red hill, first they champ, then they stamp, then they stand still.
I can only be played on a windy day
