Vampire Lenore. Okay so I have lore. Lenore doesn't know what she looks like because she doesn't appear in photos and in the mirror so Annabel Lee Painted her. This is the painting
So the day that the tree landed on her and killed Theo was the day she turned. The Vandernacht's are vampire hunters and didn't want to off their child so they hid her in the attic saying she had "gone mad." Annabel a human, shows up and knows this because of the agreement she has with Lenore's father but ends up growing extremely fond of her. Knowing that Lenore doesn't know what she looks like and the fact that she is in love with her she painted Lenore and gave it to her the day that she left. While Lenore was upset she couldn't bring herself to destroy all Annabel's hard work. She definitely cried on it. The last memory and gift from her bestest and only friend.
