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 left the royal capital on a journey, 
planning to pass through this city
Ich hatte vor, auf dieser Route
Dejé la capital real
y pasé por aquí de camino
Dejé la capital real
y pasaba por aquí de camino
Je pensais aller de cette ville
vers l’ancien territoire du roi démon
Sono partita dalla Capitale per raggiungere, 
attraversando questa città,
Deixei a Capital Real com intenção
de passar por esta cidade
Я выбрала путь из столицы
через ваш город…
