You mean Salazar SLYTHERIN?! Challenge
Rules:
Harry somehow goes back in time to the Founders' Era and meet Salazar Slytherin.
They eventually become friends.
Harry returns back to his 'normal' time but retains a mental connection with Salazar.
While in his 'normal' time, he is detained by Aurors for some reason and they find out he met Salazar(although they don't have to believe him).
He escapes and manages to travel back to the founders' time, or Salazar somehow comes forward to 'modern' time.
The story can be slash, or not. It's your choice.
