Upon a pale horse... (The Mists of Ravenloft)
Nathan De Rossi
Nathan De Rossi was the head of a wealthy family in Borca, whose first wife died at a young age and whose children were petty and cruel. Determined not to give any of his children an inheritance, he married Claire (who was young enough to be his daughter) and left all his possessions to her.
Nathan died nine days after marrying Claire.
