HP: My Cheat Is the Primordial World

Brian Glosk transmigrated to Britain, thinking all he wanted was a simple, happy life. But an unexpected letter of admission made him realize this was no ordinary world. It was a world with magic, and the magical world was clearly not as simple as the books made it seem...

The Church, heretics, evil gods from the void... One danger after another cast a pall over the entire magical world, while the Raven's Claw continued to walk the world's edge, guarding it.

Expect thunderbolts and some potentially cliched tropes. There's a slight wizarding aristocracy setting, but only those whose ancestors owned fiefdoms count as nobles. There may be some politically sensitive content.

Pairing undecided.

Theme: Time passes quickly, but the convictions in our hearts remain unchanged.
