To summarize what we know from what has been confirmed: It looks like it was Ursula who burst out of the locked Lorebook Martin opened This caused the flood, which flushed out the Lore items into the realm of Lorcana The flood of ink has changed the world, creating or changing the Inklands Purple seaweed, pools of black ink, and shadowy tendrils are shown across cards and art Ursula has a secret contract, was looking for lore, and is now finally enacting a plan There is a shadow storm and a mysterious structure at the edge of Lorcana Now, more has been revealed through a trailer, card art, and a new box set
She quests for one lore , so she's a good option to play to start earning lore early
That results in some wonderfully ridiculous mashups like Jafar crooning 'Part of Your World' from The Little Mermaid
Emerald is the only ink with characters who actively punish opposing players for challenging them
These two Ink types complement each other very well as the already good stats of Steel Glimmers can be bolstered by the effects of Emerald Item and Glimmer actions and effects
They feature dual-ink character cards for the first time in the game
