The Seven Elements Of Power is a book that can be read in the game Luminous Arc, the first game in the Luminous Arc series.
The book The Seven Elements Of Power can only be found in the libray of the Ever Garden in the game. In the in-game selection of three texts viewable when visiting the Ever Garden's libray it is the second title from the top, in the middle.
The book's meaning is somewhat more obscure then many other titles in the game. It details the Seven Elements in the game. Each character has an Element that represents them in-game, which affects certain aspects of battle. Each of the seven witches of the original Luminous Arc title also represent one of the seven elements.
The seven elements are: Nature, Fire, Wind, Water, Light, Darkness, and Thunder.
