The Mother Goddess Statue
As soon as the final prerequisite quest is complete
See the Mother Goddess Statue restored
When Link visits the Forgotten Temple - which he is sent to as part of The Dragon's Tears Main Quest, as well as the Goddess Statue of Power, Goddess Statue of Wisdom or Goddess Statue of Courage quests, whichever one he encounters first - he sees the Mother Goddess Statue lying, toppled, on the floor as a result of the Upheaval.
When he visits the Spring of Power, Spring of Wisdom and Spring of Courage, the Goddess Statues there ask for the claws of their respective dragon to allow them to send power to the Mother Goddess Statue towards its restoration. When all three have done so, the final one will direct him to the Forgotten Temple to see the Mother Goddess Statue restored.
There, the Mother Goddess Statue thanks the "devoted swordsman who offers his prayers", and grants him a White Sword of the Sky as a reward.
