Rest and enter the large gate to fight a familiar duplicating enemy.

20Chapel after the battle: find Reese's Ring and read the notebook
After victory, enter the rear chapel and collect Reese's Ring.

Interact with the notebook beside it to trigger a cinematic.

The memory follows Reese and Ozma. Despite Hismar's defeat, evil remained, and Ozma wanted to eliminate it entirely.

On the intended wedding day, the emperor demanded Reese become his consort. Her attempt to flee failed.

She could now trust only Plebus. This part of the memory ends here.
