Introduction

Team Flash struggles to protect Central City without The Flash. Oliver Queen deals with grief as he attempts to protect the city and raise his son, William, at the same time. The Legends have been disbanded after creating a temporal mess. A grief-stricken Kara Zor-El chooses to ignore her humanity, pushing away the people closest to her.

Old threats return. New threats rise. New bonds are forged. The world is on the brink of chaos and anarchy. It is time for Earth's finest heroes to band together once more and save the world from destruction.
