MC could've met Dumbledore
So i was just thinking what year Dumbledore had first gone to Hogwarts which i did and it came up as 1892, and so for some reason i then searched up what year is Hogwarts Legacy in which is in 1890, and our MC is in their fifth year of Hogwarts, there's 7 years in Hogwarts. 5+2=7 and 1890+2=1892 so there is exactly 1 year where our MC is on their last year of Hogwarts and Dumbledore is on his first year of Hogwarts and where they could've met.
I might be the only one who knows this but i haven't seen others talk about so why not
