The Caretaker Quest - Part 6

This is part 6 of the "side quest" for "Disappearing Hogwarts".
An unofficial alternate timeline based on HeadQM´s highly praised quest, Disappearing Hogwarts.
Reading the original story is not exactly necessary but heavily encouraged since this quest will contain references to it.
Created mostly as a place to wait while HeadQM was away for a while but slowly evolved into his own thing.

Quick recap so far:
>Recently graduated Ravenclaw student is hired at Hogwarts as the new Caretaker.
>Merlin somehow ended up inside your head.
>Harry Potter´s daughter died, letting Salazar Slythering (previously stuck inside her head) free to continue his quest to control The Beast, an all powerful ancient creature accidentally created by Merlin.
>Is currently looking for a new body.
>So is The Beast.
>Your girlfriend almost died.
>It is a now a race against time to stop Salazar and The Beast from causing irreversible damage to everything in existence.
>Hogwarts is slowly becoming an administrative mess now that Harry Potter himself disappeared.
>You now have a private investigator lurking around Hogwarts and might have suspicions about you.

What will happen now? Let's find out!
