The era in which Harry Potter's parents lived in the Harry Potter series is called the parent generation.

The main characters include: James Potter, Sirius Black, Remus Lupin, Peter Pettigrew, Lily Evans, Severus Snape, etc.

After the popular science, here is the introduction.

1971.

The ignorant little wizards happily boarded the train to Hogwarts.

The Death Eaters developed silently in the dark, and no one knew whether the people around them were enemies or friends.

Voldemort's power will soon reach its peak, and Hogwarts will become the only truly safe place in the British wizarding world.

But there is no savior favored by fate here, only an incompetent Ministry of Magic and endless crises that are emerging more and more.

The dark ages are coming.
