Thanks, Karena. Yes, wanted another girl as OH has enjoyed being the 'man of the house' and wanted it to stay that way... if that was the only condition he set on a second MC, I thought I'd take it!
The name was a bit of a word association thing... I like names to be symbolic or mythological (i.e. Freyja is named after the Norse Goddess of Beauty, Love and War - appropriate to her character!). So I wanted a magic/ gothic name for a black smoke, and OH suggested Salem (as in town in Boston where the alleged heathens were burnt for being witches) but it sounded like a boys name, so I suggested Pagan. OH wasn't keen but was inspired with Wicker (as in the Wicker Man) and so we settled on Wicca, as in white magic. Once he'd said it, I knew I didn't need to keep thinking about names as it's perfect!
