Ghost in Black

After the war of Hogwarts there's been an abnormal and indifference of chilling hauntings. Except, these hauntings seemed to be beneficial as Minerva found her office magically organized and students became... well behaved. For the most part at least. And further sightings have shown a ghost in black, protecting both students and his secret vials... But Harry was determined to unravel the vials.--' Passing through each student as though a reminder of the coldness... but it emitted a sense of warmth. The feeling of odd familiarity'

Helloo, this is my first ever HP fic as I only really write GO fics. I had the random idea of a ghost Severus Snape rooming Hogwarts as a protective ward. As I am quite obsessed with his overall character. I plan to have around 3 chapters of in this. Updates are not scheduled.There will be platonic Snily mentioned into later chapters.
