Prompt: Fame.
Disclaimer: I don't Harry Potter. JK Rowling, the queen of the nargles, does though.
Fame is a fickle beast, but he had learned how to tame it. He had directed it, used it, twisted it, and redirected it. He used it as a means to his ends. He molded it and abused it. He took the memories of true heroes and made them his own.
Then it had crashed around him, and he was left with no memory of it. Just a painful longing for something he could never again have. A painful need to be known and recognized, not that he knew that was what he needed.
His name once was Gilderoy Lockhart, and now he was just another smiling face to the wizarding world.
And now the only memory of him lies in the minds of the two boys who helped him end up that way.
A fitting end, I daresay.
AN: Depressing, no? One that was fun for me to write because it finally show that him being oblivated is a far worse punishment than we thought, at least, in my opinion.
