Synopsis

Eren is confronted by the ghost of his great-aunt, Attia Pendragon, who reveals she died alongside the original Eren, and that the current Eren is not the original one, likely a different soul in his body. She explains that the Pendragon mausoleum holds the family's power and can only be opened by a Pendragon successor who can make a pact with Soldrake, a task the original Eren failed at. Attia tasks the current Eren with opening the mausoleum and thus restoring the family's fortunes and his command over the Vassals.
