Miquella’s withered arm
As we learned in Elden Ring’s base game, Miquella is the twin brother of Malenia, who was cursed with an inability to age. Miquella encased himself in a cocoon in order to grow alongside the Haligtree, which he created in an attempt to save Malenia from Scarlet Rot, but that cocoon was then stolen by Mohg, who you can fight in the base game.
The trailer begins with the Tarnished standing in that same spot that you fought Mohg, before showing us a close-up of Miquella’s cocoon. As YouTuber Iron Pineapple correctly predicted in April 2022, Miquella’s cocoon (and his “withered arm” mentioned in the trailer by Melina) are the point of entry for the DLC. You gotta go and touch that icky thing to get into the Shadow of the Erdtree land.
