The Outlaws are broken up. Roy readies his arsenal for an attack on the League of Assassins with the help of the Untitled, Jason is trying to figure out why Bronze Tiger wants him to lead the League, and Kori is busy laying the smack down to Essence until she spills on whats really going on. When Essence learns of the Untitled helping Roy, she finally decides to tell Kori the truth.
Before we find out what's going on here, let's take a walk through the League's ancient city shall we. This serves as an introduction of sorts to all of the League members we have seen recently. December Greystone who is a blood mage, Rictus who is sort of techno-magic, Cheshire who is still pretty interested in seeing Roy again, and Shiva, who is ruthless.
Back to Kori! Essence tells Kori that many centuries ago, Ra's al Ghul talked his way into being trailed by the All-Caste and Ducra, eventually leading to a pact of sorts between the League and All-Caste, which meant the League had a pact with the Untitled through the All-Caste. The connection between all of this is that the lazarus pits are sort of off shoots of the well of sins, which gave the Untitled their power. Ra's built his city over the well of sins, as sort of a middle ground between the All-Caste and Untitled, but now that the Untitled have broken the pact, they're all too eager to get back to the well, and pretty much doom the world.
Back in the League's city, Jason is still trying to be convinced to work with the League who is all "The Untitled is bad!" and won't exactly tell him why Talia believed him to be their savior of sorts in this battle... which is starting right now, because Roy shows up with enough weaponry strapped to his back, that even 90s Rob Liefeld would look twice at.
