"Mary" (she/they)
Background
The more experienced of the two, "Mary" has worked with the fey for years before "John" came along.
She acts in an overly familiar way that comes off as a bit careless and unprofessional, yet is quite good at her job.
Before there were fey mediators, a special unit of the police handled fey disputes, the results were mixed. That is where "Mary" started their career. Mary was one of the first fey mediators switching to that role the second it was possible.
