Cannon

By 1985 she became the Astronomy professor at Hogwarts

She was known to give large amounts of homework to students in their fifth year and to those who continued Astronomy for sixth and seventh

She attended the Yule Ball with Barty Crouch Jr, who was posing as Alastor Moody. Sinistra danced a nervous two-step with him, careful to avoid his wooden leg, and seemed rather uncomfortable

Her patronus was a polar bear

Her boggart was ending up alone

Was friends with the Edmund Avery since childhood

Was in a friendship group with Emma Vanity, Florence Greengrass, Septima Vector and Bertha Jorkins

The girls were very popular in school and were sort of IT girls

They were also close friends with Xenophilius Lovegood

Later on in Hogwarts she was also friends with Edmund, Bruce Mulciber, Juliette Wilkes, Severus Snape and Charity Burbage

While in school she was with Florence. They started dating when they were in their fifth year

Right before their seventh year Florence started cheating and Aurora found out, so she cheated back but with Septima

When Bertha found Florence kissing Killian Gibbon and told everyone, Aurora came clean about how she already knew. All of this drama caused the group to crumble in on itself

After the war Aurora lost touch with Bruce and Edmund but remained friends with Severus and Charity (Juliette was dead :( )

Aurora started working at Hogwarts in the 80s but for a while considered turning down the position because she didn't want to run into Septima, who was already a professor there

While working at Hogwarts she got closer to Charity again and in 1994 they started seeing each other

I'm 1996 Severus visited Aurora and Charity in their quarters and told them that they couldn't speak to each other anymore. As a parting gift he told Aurora that Bertha was dead and how she died

Aurora then told Septima about Bertha and the two agreed to put their differences aside while the Death Eaters took over Hogwarts

Before the Battle of Hogwarts, they got the news of Xenophilius imprisonment and told Emma and Florence everything. The remaining four of them patch up their differences and fight in the Battle of Hogwarts in their name

Right before he died, Severus told Aurora how Charity died and told her that it was Edmund who got her killed as revenge on him

Aurora was the one to kill Edmund as revenge for Charity
