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.
Arrow of void, drive a stake into the 
boundary between Heaven and Earth!
O Alptraumklinge, ramme
einen Keil durch sie! Gravity Abyss!
Saeta del vacío, clávate
en el límite entre cielo y tierra,
Saeta del vacío, clávate
en el límite entre cielo y tierra,
Flèche du néant,
perce la frontière entre ciel et terre !
Freccia del Vuoto, insinuati nel confine 
tra la terra e il cielo!
Flecha do vazio, crave uma estaca
na fronteira entre o Céu e a Terra!
Стрела пустоты, воткни кол
 меж границей неба и земли!
