New Characters in Harry Potter

Since my last post about the main characters in the novel Harry Potter and the Dealthy Hallows, several new people have been introduced into the story, and others have been better developed by the author. One new character is Luna Lovegood, who comes into the story when she meets Harry and his friends in the cellar of the Malfoy Mansion. Luna is very kind to everyone around her. She is very concerned about leaving the cellar without Harry and when he suggests that she flees to safety without him, Luna responds, "Harry, we want to help you!" (468). Luna is also very unique. She is different from most other witches her age and is fascinated by bizarre creatures and objects. Luna seems to be motivated by her hope of helping Harry defeat Lord Voldemort so that the world can once again be a peaceful place to live for wizards.
Luna is stuck in the Malfoy's cellar with another key character, the goblin Griphook. He has a grumpy disposition towards those around him and seems to prefer being alone rather than with wizards. He id very offended that wizards and witches pass goblin-made goods amongst themselves and is motivated by his hope of obtaining these goods one day. For instance, Griphook only agrees to help Harry gain access to a goblin bank vault if he will award him with a valueable goblin-made weapon in exchange. The goblin insists, "I want the sword. The sword of Godric Gryffindor," (505). Griphook's eye is also caught by a gem-encrusted tiarra which is owned by Ron's aunt.
Griphook's greed is nothing compared to that of another character, Lord Voldemort. The dark lord (whose former name is Tom Riddle) is cruel and vengeful. He will turn on even his allies when he is upset. Peter Pettigrew, a follower of Voldemort, is attacking Harry Potter when he is overcome with sympathy for the boy. Instead of strangling Harry with the artificial hand given to him by Voldemort, Pettigrew releases him. However, Pettegrew is strangled by the hand and the scene is described as, " The silver tool that Vodemort had given his most cowardly servant had turned upon its disarmed and useless owner; Pettigrew was reaping his reward for his hesitation, his moment of pity; he was being strangled before their eyes," (470). This cruel deed of the dark Lord reveals his anger and hunger for revenge. Voldemort is motivated by power, and he hopes to one day have control of the entire world, both of wizards and non-wizards. All of the new characters in the novel are quite different and play big roles in the novel.
