Days later Clark reaches the North Pole, where he takes the green crystal and throws it miles into the distance, where it melts into the ice and begins construction of a gigantic crystalline structure, a Fortress of Solitude. Inside Clark finds a matrix table of crystals; placing one into an aperture, he activates a dimensional communicator that reveals the spirit of Jor-El, his true father. Jor-El provides the youth with his true identity of Kal-El and takes his son on a journey through time and space to complete his maturation, educating him on the universe and on his purpose in life. When the journey ends, Kal-El has aged twelve years to the age of 30, Kal-El is now clad in a red-and-blue costume with red cape and bearing the crest of the House Of El, ready to fulfill his purpose of protecting his new home world in the memory of Krypton.
