Slytherin Headcannon

the-unobtrusive-bathtub:

Inspired by this post: when Slytherins graduate, they write a single “tip to success” on a wall somewhere in the common room, whether it’s how to brew a perfect anti-paralysis potion or how to get on a certain teacher’s good side.

This becomes a sort of shrine, “the wall of erudition,” with candles and everything – I feel like Slytherins would also be a little superstitious, so there would be some offerings there, and many muttered prayers in front of it during exam seasons. It would also be a fantastic record of the lives and histories of the individuals who wrote on it.
