Mortmain is Back, or is He? DISCONTINUED

My first Fanfic, don't judge too harshly. Starts out with the birth of James, Tessa and Will's son. A few years after James is born, one of Mortmain's colleagues (acquaintance, if you must) shows up for revenge. Is he after Tessa like Mortmain was? Will the Shadowhunters survive his wrath and attempt at vengeance? Will he succeed? Read to find out. Modernized, you'll see why.
