Yes, and she was the only thing he had in life; he lost his family to Mutations at a young age, and his older brother was killed by a raptor. His paranoia made him abusive to anyone who came near Lionissa, so she eventually dumped him.
He sexually harassed her twice. Ehlax saved her both times.
First time was when he tried to get her back. Second time, she found him and tried to reason with him in order to prevent a war, but he kept her prisoner.
