Diablo, Shera, and Rem head out to the plains to test out new magic. While using said Flight Magic, Diablo spots the light of magic energy rising up from deep within the forest, so he makes haste towards its source. However, his spell gives out half way, and he goes plummeting down!

When he lands, he finds the Head Priest, Lumachina under attack from the Paladin, Gewalt.
I shall remain with the Demon Lord here.
Ich werde ebenfalls hier … beim König …
der Dämonen … verbleiben.
Y yo me quedaré a acompañar
a la señora demonio.

Я, Эдельгарда… останусь вместе…
с Владыкой Зла… вот.
