The Eyes of Graphorns (Professor Sharp x mc)

After the battle of Hogwarts against Ranrok and his followers, nothing is the same for Elaine Hopkins. Her mentor is dead, and she finds herself with a new responsibility as the guardian of the last repository. She finds support in Aesop Sharp, who escorts her after Fig's death and slowly gains her trust.
After her graduation, she disappears for seven years and eventually returns to Hogwarts, where after a long search and wait, she is finally reunited with her former potions professor. She and Sharp grow closer to each other, but soon, they discover that their destinies are interwined more deeply than expected.
