The Valley of Power is a region of Eternia spoken of in legends. The valley is guarded by the Mother Roe, a fierce bird-like creature that makes its nest there. The valley contains a spring which is said to yield water only one day every thousand years; the water from this spring bestows great power and bravery to those who consume it.
