Mags has an uncanny ability to make plants bloom. Always has water with exactly the right PH balance. Her other talents lie in... special research, and she applies that to making sure her necklaces have a special je ne sais quoi.
Technically, she has five jobs. This; helping Connor with his job (she gets 25% of the paycheque); and 3 remote-working IT jobs that she has rigged up to automate. None of her employers have noticed, and she's good enough that they never will.
She's Connor's older cousin, and lives with him and his… friend.
