Benjamin Thackerey

"Ben would rather be in a nice quiet room doing nice complicated sums. Instead he's found himself working alongside a pair of convicts who can't find even find it in themselves to wipe their shoes before entering the office. At least he has his dedication, his meagre magical talents, and a good solid broom to tidy up after the office interlopers."

Trivia

 * Ben's name comes from originally being referred to as 'bean counter' in the scripts. He'd probably be pretty mad to know this.
 * Ben was originally going to be two separate characters, a wizard and a beaurocrat, but was consolidated into one.
 * Although not canon, reading Ben as transgender is a popular headcanon, which Kate has been supportive of.
