While the justice league members were in the watchtower on their daily brake something silver yet formed like a crystal. It floated near the watch tower and then was drawn into the atmosphere of the earth which pulled it down as the members watched and after a moment it was slammed into the ground. After awhile Superman, Hawkgirl and wonderwoman and the flash went down to earth, the impact they saw was sticking out like a crystal. It was pointed several random ways.
