"In fact, Lig never formally resigned his editorship—he merely left his office late one morning, and has never returned since. Though well over a century has now passed, many members of the Guide staff still retain the romantic notion that he has simply popped out for a sandwich and will yet return to put in a solid afternoon's work. Strictly speaking, all editors since Lig Lury Jr., have therefore been designated acting editors, and Lig's desk is still preserved the way he left it, with the addition of a small sign that says LIG LURY, JR., EDITOR, MISSING, PRESUMED FED."
