Elminster got with Mystra first. Even wilder, Mystra magically changed Elminster’s gender as punishment (Elminster got his start as a thief) and made him serve as a female human cleric of Mystra for a while. Only when he was back in her good graces did she gender swap him back so she could bonk him.
All of this was before he was even a wizard. Elminster has seen some shit.
