God curses the serpent after deceiving Eve in the garden, and creates "enmity between [the serpent] and the woman." In the "Harry Potter" series by JK Rowling, the serpent is a symbol of evil, and near the end of the books, is the only piece of evil left to destroy before good can truly be restored.

The "tree of life" is used as a symbol in the Bible as the only thing that sets Adam and Eve apart from God, (eternal life), after they come to know good and evil. This, "tree of life" is also an important symbol in Islam beliefs, however, here it is represented as the "tree of immortality", and is known as the "only tree in Eden".
