Gotham City hides a secret, a 40,000 year old secret lying just beneath the streets. The dark history of Gotham City is revealed as the streets become over run by a mysterious force known only as The Horizon. Batman forms a team of unlikely combatants who must swear a secret oath or a “Shadowpact” to rid this evil from the streets of Gotham before it swallows the world.
