How I feel right now after finishing the 7th Harry Potter book knowing I can interact with one of the biggest fandoms in the world.

Soooo yeah I am super new to the fandom and would like fics recommendations (my native lenguage is spanish but english fics are fine aswell). Also, I'm 19 so they can have content warning shi in it :P

I only heard about "All the Young dudes", should I start there?

Okay, so this part seems easy to answer on its face:

Harry only ALMOST died, so the horcrux was only almost destroyed. But if Fawkes had let Harry die, then theoretically it should have also destroyed the horcrux.

But the REAL question is:

What if Harry had died at any other point in the series from something other than a proven way to destroy horcruxes?

Would the horcrux have taken over Harry's body after he died because the horcrux can't be destroyed through ordinary means? Can Harry not actually be killed because he's a horcrux and that's actually how he survives every dangerous encounter in the series?

What if someone dropped a boulder on Nagini or cut her in half with a regular sword? Does the blade not cut through? Does she heal or have to survive maimed in perpetuity? Do living horcruxes not abide by the same rules as inanimate ones so don't require extraordinary methods to destroy them?
