Xenoblade Chronicles 3: Part 87: Queen's Key & The First Day of Prison

Ouroboros infiltrates Agnus' Li Garte Prison Camp and meets Ghondor, Monica's daughter, whose violent nature keeps the prison in check. She refuses to help save Aionios and wants to minimize deaths while keeping the city out of the escape plan. After witnessing the city, Mio’s worldview shifts, and Ghondor eventually gives Ouroboros a brooch that is a key to Cloudkeep, needed to awaken the Agnus Queen. Ghondor plans an escape during a training exercise on Daedal Isle, though Taion and Eunie are uneasy. Meanwhile, Lanz and Sena bond over confidence issues. Prisoners must gather materials in the Perimeter Woodland, with death for suspicious activity, while the guards treat them cruelly.
