Slytherin!Abused!Harry with mentor Snape
does anyone know the name of the fanfic where Harry is sorted into Slytherin and is mentored by Snape?
Things I remember:
-the head of Slytherin house is always called the Basilisk
-Harry talks to Salazar Slytherin through a portrait/locket
-I am pretty sure there is a scene/chapter where Harry is upset and it manifest into Snape smelling fish/hearing and old fishing son his dad use to sing
-something about a seaside cottage that Harry and Snape go to during school break (I particularly remember Easter)
-Snape's mother was abusive and his father was good
-pretty sure it was posted on fanfiction.net, but I could be remembering that wrong
