Yves Grosclaude was a Havenite citizen and diplomat.
He was originally a Dolist, and served as the Republic of Haven's ambassador to the Star Kingdom of Manticore under the Pritchart administration. He and Arnold Giancola were old friends and conspired to alter diplomatic notes between the Republic and the Star Kingdom. This eventually led to the Second Havenite-Manticoran War. (HH10)
