We call this piece the Eye of Leviathan. Levithan is an ancient serpent who holds great knowledge, both white light and dark. He has received this magic from the Tree of Life, which runs through the middle of existence.
When using this piece you will be able to conjure the presence of Leviathan. When you use this piece you will be able to see through his third eye. You will be able to wrap your presence around the Tree of Knowledge as if you were a serpent yourself. This will allow you to absorbs its energies and manifest the type of magic that you want into your life.
