Kronos

Towering over his surroundings and possibly the last of his kind, Kronos is a Mark IV Formis "Colossus". 
Found buried in the dirt by Group Alpha to the north of Westbrooke, when investigating him something triggered an awakening. He emerged from the soil leaving massive hole, and walked straight into the ocean.
He was heard to have said that there is something "inside" of him, which Group Alpha has discovered to be a Vestige. Although they managed to locate him on Fallen Star Island, they were unable to retrieve the item from within him. They left the island with the intent of returning later on, but were shocked to learn that Kronos and much of the island had been utterly eradicated, and the vestige taken to Westbrooke.
