Greetings DLP members.

Looking for Harry Potter fics.
Where Harry aim to destroy the current culture of Britain Wizardry.
It isn't because he was betrayed and shoved into Azkaban.

He want vengeance vs the DE, vs the Ministry for enabling or sympathize with the former, vs Dumbledore (and his supporters) for doing nothing.

Are there Sirius Black taking vengeance ?

In some ways in 1991 despite the dark lord being defeated, his followers (minus the rabid ones) manage to silently to take over the government and culture.
If Dumbledore died due to old age, they were left with no opposition.
This fertile grounds can breed a counter movement to see the slights and wrongs against them fixed.

Here is an example of Nevile having enough.
