Having heard everything from Kiana, Lucius understood that only more investigation into this would get them any chance at getting the answers. Besides the obvious value of Keith as a test subject, he was also iimportant,as he could be used as the weakness of the Viscount.
While the Viscount had three children of his own, Keith was the eldest and was the chosen heir. His other children were much younger, with a girl being nine years old and a boy of six years old.
Meanwhile, Keith was twenty five years old and was undoubtedly going to be the heir of his territory. If Keith was gone, the Viscount may fall in trouble, as it would take him far too long to train his other children.
His second child was a girl and was not someone who he wanted to be the heir. If she was the only child he had, it would have been possible, but since he had another son, he would be the one who would have to become the heir.
