Burn it All Down (смешанная)

Regulus woke up with a dark mark on his arm, sworn by his parents to serve Voldemort. He nearly died from an infection, but Severus saved his life.
During the attack by Voldemort & Dumbledore, which killed Regulus & Jamie, the septuplets accidentally time-travelled to save their lives. They time travel away during the attack in November 1984.
They end up in 1964, and since the septuplets are born, werewolves are typically raised in Fenrir's pack alongside Remus. Since werewolves don't lose their minds on full moons, they aren't ostracised, and they attend magical schools like everyone else. They are raised as Remus's pack siblings and are very close as a result.
This story will be in two different timelines, but I will make things clear when it happens. I will also combine chapters from the same time/timeline to help decrease confusion.
There is a lot of questionable consent due to not being allowed to say no to your elders, professors, etc. Everyone has gotten so used to rape of any kind, that it doesn't cause anyone to bat an eye at any of it anymore.
Chapter 1 is about world-building and provides more information that you need to know.
Chapter 2 is when the real story begins
