**Brian Macmillan**, also known as **Buck Macmillan**, is an Australian retired Auror and the father of Matilda Macmillan.

## Biography

### Family Lineage

Buck is related to the Noble House of Macmillan, as his squib father Jacob had been born into that house. When it was discovered he had no magic the twelve-year-old Jacob was given twenty galleons worth of Muggle currency and placed on a boat to Melbourne. Jacob eventually worked his way up from stable boy to owner of the Waltzing Matilda's saloon in Wagga Wagga, married a muggle-born witch, and sired a wizard son.

### Early Life

Buck was most likely born sometime in the 1930's to Jacob Macmillan and his Muggle-born wife. He was raised in the Magical Commonwealth of Australia, and went to an unknown Magical School where he graduated with grades high enough to eventually join the Auror Corps, where he trained, among others, Auror Nguyen Park.

Buck eventually married a woman named Nora, with whom he owned Waltzing Matilda's, which they in inherited somewhere around 1953, and Nora gave birth to a daughter around March of 1963, naming her Matilda after the bar. Nora Macmillan passed in 1975.

At some point before 1980 Buck acquired a Thyalacine named Daisy.

### Lazarus White

In January of 1980 Regulus Black moved to Wagga Wagga under the name Lazarus White. Matilda, who dubbed him Rusty, hired him as the Waltzing Matilda's new bartender and bouncer. Matilda and Regulus fell in love over the course of the year, and were caught sleeping together on Christmas of 1980 by Buck. Regulus revealed his true name and face to Buck, who gave him permission to be with Matilda if he joined the Australian Auror Corps.

After graduating from the Auror Corps Regulus married Matilda, and in 1984 they had a son named Leo Brian White, after his grandfather. Regulus continues working in the Auror Corps, and him and Buck take down and kill the Werewolf Clarence Tully, though not before Tully kills Daisy. Clarence's brother Eustace swears revenge, and eventually leads his pack on an attack on Wagga Wagga, where they kill Matilda and Leo. Regulus tracks down the Tully Pack and kills them all with Fiendfyre and a Killing Curse. Buck convinces Regulus to flee the country instead of giving himself in, leading Regulus to steal the identity of Gilderoy Lockhart. In 1985, after Regulus had published Wanderings with Werewolves, he sent Buck a copy, alongside a Thylacine named Reggie.

Buck retired sometime between 1984 and 1993.

## Physical Description

In 1980 Buck was said to look somewhere between forty and fifty, with a thick bushy mustache. He wore a mish-mash of cowboy gear, Wizarding clothing, and Auror apparel, as well as a black fedorah.

## Personality & Traits

Buck is skilled at reading people thanks to his Auror training, as he was quickly able to deduce that Regulus had come to Australia to atone for something he had done in Britain.

## Magical Abilities & Skills

Buck is presumably a skilled duelist, as he was allowed to join the Australian Auror Corps, though he admits the Australian Aurors aren't as well trained as their British counterparts.

Buck is capable of casting a corporeal Patronus, which take the shape of a Flemish Giant Rabbit.
