The Caretaker Quest - Part 7

This is part 7 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.
>He is currently now trapped inside a poor and weakened girl named Artemis.
>This bought you valuable time while you learn how to contain The Beast
>Hogwarts is slowly becoming an administrative mess now that Harry Potter himself disappeared.
>You have a private investigator lurking around Hogwarts and is heavily suspicious of you.
>You also learned an ancient powerful spell
>Fought Artemis while she was possesed by Salazar and took her to St.Mungos after defeating her.
>Merlin regained some of his senses back and you are now lurking around St.Mungos looking for an explanation.

What will happen now? Let's find out!
