This Year a Shadow from Japan's past comes back to terrorize the planet into submission but a newly created group with Harry and his inner circle has emerged to take the lead but with Duncan Rosenblatt banished from this dimension things will get tougher for the Forces of Light but the Forces of Darkness will find that the Light and the Human Spirit is not so easily broken.
