Maid of Lidia:
He took her memory and put it in another body. He gave only her knowledge and grievances to Triol, who used them to create the Lord of the Forest of Dead, Lidia von Hellmann.
And the memory of Lidia was put in the corpse of the maid Rose who was the best friend of Lidia's. Rose was then resurrected as the first vampire when the Lord was created.
To prevent her from remembering anything, the hairpin, dress and diary are hidden separately in the forest. To prevent Lidia von Hellmann from remembering anything.
"So who are you?"
