On the shores of the sea, Gandalf turned and looked back, seeing in his mind all the lands he had wandered and all the evil he had seen and countered – monsters, wicked Men, plagues and darkness almost impenetrable.
But there was beauty too, and he had friends yet remaining among Hobbits, Dwarves, and Men. He was sorry to leave these shores, but there was an aching weariness in his bones, and he yearned for home.
As they approached Valinor’s white shores, Gandalf set his staff to his last rocket, laughing with Bilbo while the Elves, smiling indulgently, shook their heads.
