The Isley family is one of Union's most affluent noble families. Pamela's father is a high ranking engineer. I...am probably going to go with some of her relatives perishing during the Elite Four attack just to move her up in the line of succession. Because I'm mean like that. ;)

Pamela herself is a fairly powerful Englightened with Grass/Poison abilities. She doesn't make use of the pheromone aspect of her abilities to manipulate others, but Palpatine could offer her some "well meaning guidance" about that?
