Characters in "The Fall of the House of Usher"

1). Narrator, a friend of the master of the House of Usher. When he visits his friend, he witnesses terrifying events.
2). Roderick Usher, the master of the house. He suffers from a depressing illness characterized by strange behavior.
3). Madeline Usher, twin sister of Roderick. She also suffers from a strange illness. After apparently dying, she rises from her coffin.
4). Servant, domestic in the Usher household. He attends to the narrator's horse.
5). Valet, domestic in the Usher household who conducts the narrator to Roderick Usher's room.
6). Physician, one of several doctors who treat Madeline Usher.

   Of course, the greatest attention is paid by the author to Roderick, narrator and Madeline. 

    Roderick Usher is presented as a weak person, who has a mental disease and a burden of the ancient family damnation on his shoulders. He is represented through the direct characterizations - as the narrator describes his appearance, mental state, all his actions.

    "Yet the character of his face had been at all times remarkable. A cadaverousness of complexion; an eye large, liquid, and luminous beyond comparison; lips somewhat thin and very pallid, but of a surpassingly beautiful curve; a nose of a delicate Hebrew model, but with a breadth of nostril unusual in similar formations; a finely-moulded chin, speaking, in its want of prominence, of a want of moral energy; hair of a more than web-like softness and tenuity; these features, with an inordinate expansion above the regions of the temple, made up altogether a countenance not easily to be forgotten."

   The same I can say about lady Madeline. She is presented also through the direct  characterizations of the narrator. We even don't here her voice. She doesn't participate in the rare dialogues in the story. Madeline is like Roderick's shadow, an integral part of him. When this part dies - Roderick dies also, he can't live without it.

   The narrator has no name, but we are satisfied with the fact, that he is a close person to Ushers to have no doubts in his thoughts, words and ideas. We feel this man loves Roderick as  a friend, as a brother. He wants to help, but he doesn't know HOW. And he tries his best even through his oppressive feelings and FEAR. Yes, he is afraid, as every of us. Because he doesn't understands what's going on, though his intuition gives him hints. And he of course confused, he looses his close friend. He feel helpless in that God forgotten place.

"From that chamber, and from that mansion, I fled aghast. The storm was still abroad in all its wrath as I found
myself crossing the old causeway. Suddenly there shot along the path a wild light, and I turned to see whence
a gleam so unusual could have issued; for the vast house and its shadows were alone behind me."

   All the characters in the story are victims of the House and the family damnation. Only the narrator escapes, as he doesn't belong to this place. The inhabitants of the house and the building itself became one whole long ago. And they disappear from the earth also together. They lived their time.
